Longest partial lunar eclipse of this century is almost here: How to watch

Earth’s shadow will cover most of the moon Nov. 18-19, and it will take its sweet timing doing it.

Celestial showtime is almost here. There’s a partial lunar eclipse on tap for Nov. 18-19 and it’s notable for how long it will last. The Earth’s shadow will largely block the sun’s light from reaching the moon, tinging our lunar neighbor with darkness.

NASA statistics on lunar eclipses from 2001 through 2100 show this month’s partial eclipse will be the longest of the century with a duration of over 3 hours and 28 minutes. Compare that with the longest total eclipse of the century, which happened in 2018 and stretched for nearly an hour and 43 minutes.

The Holcomb Observatory in Indiana shared a handy graphic showing what to expect from the eclipse, which will cover most of the moon. «This will also be the longest partial lunar eclipse in 580 years,» the observatory tweeted.

What a partial eclipse looks like

Lunar eclipses don’t have the same dramatic appearance as a solar eclipse where it looks like someone is carving a black hole out of the side of the sun.

During a lunar eclipse, the moon darkens and sometimes takes on a reddish color. For a partial eclipse, Earth’s shadow doesn’t completely cover the moon. Partial eclipses are still fantastic experiences.

«Partial lunar eclipses might not be quite as spectacular as total lunar eclipses — where the moon is completely covered in Earth’s shadow – but they occur more frequently,» NASA said in a skywatching update. «And that just means more opportunities to witness little changes in our solar system that sometimes occur right before our eyes.»

When to watch the lunar eclipse

The eclipse will be visible to a large area of the globe across the evening of Nov. 18 and into Nov. 19. Exact viewing times will depend on your location, but at least some of the eclipse will be visible in most of the Americas, Australia, and in parts of Europe and Asia. The US will be in a great position to catch the eclipse action.

Head over to Timeanddate.com and search for your location to get your times. If you want to watch the full process, you could be in for a long night. For example, the partial-eclipse phase will kick off at 12:18 a.m. MT on Nov. 19 for me in Albuquerque, New Mexico, and reach its maximum at about 2:02 a.m. I’ll probably aim to set an alarm for closer to maximum rather than stand out in the cold for hours.

How to watch the lunar eclipse from anywhere

You have online options for following the moon action. These video feeds are a good fallback if you encounter cloudy weather, or if you just don’t want to stay up late or get up early to watch the eclipse in person.

The Virtual Telescope Project will go live with coverage of the eclipse at 11 p.m. PT on Nov. 18 (7 a.m. UTC on Nov. 19). VTP is collaborating with astrophotographers from around the world along with offering live commentary from astrophysicist Gianluca Masi.

Timeanddate.com has arranged for its own livestream starting at 11 p.m. PT on Nov. 18.

Eclipses aren’t everyday occurrences on Earth, and they’re not always easily visible. While some viewers might have to contend with middle-of-the-night scheduling for this month’s celestial event, it’s worth taking a moment to marvel at how the moon, the sun and our planet are connected as residents of this solar system.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

 
As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.

Wild Weather Ahead: Here’s How 2024 Is Shaping Up After the Hottest Year on Record

The climate crisis is impacting communities around the world. Here’s what to know about dealing with extreme weather in 2024.

We just lived through the hottest year since recordkeeping began more than a century ago, but before too long when we look back at 2023, it might not stand out as the pinnacle of extreme heat. 

That’s because it’s unlikely to be the only hottest year that we experience. Our climate is changing, growing warmer due to the emissions from burning fossil fuels, and our weather is changing with it. It’s possible that this year may turn out to be hotter still.

In March, scientists from the EU’s Copernicus Climate Change Service said February 2024 was the hottest February according to records that stretch back to 1940. The news came on the heels of their report in early January that, as expected, 2023 was indeed the hottest year on record. Temperatures closed in on the critical 1.5-degree Celsius rise above preindustrial levels, after which we will see irreversible damage to the planet. These aren’t freak outliers: The extreme heat we’re experiencing is something we’ll need to be prepared to deal with on a much more regular basis, along with storms, floods and drought.

Later in March, the US National Oceanic and Atmospheric Administration issued its spring outlook, predicting that most of the continental US and Alaska will see above-average temperatures from April through June. The risk of flooding, it said, will ease during the three-month period because of «historically low winter snow cover» in large parts of the country.

A key trend highlighted by the US government’s Fifth National Climate Assessment, published in November, was that climate change is provoking extreme weather events across the country that are both more frequent and more severe. It pointed to an increase in heatwaves and wildfires in the West over the past few decades, the increased drought risk in the Southwest over the past century and more extreme rainfall east of the Rockies. Hurricanes have also been intensifying, as those who have found themselves in the path of a storm know all too well.

You’ll need to be prepared. Extreme weather is going to have a widespread impact on industry, society and individuals. Last year in the US there were 25 extreme weather events with losses amounting to over $1 billion that resulted in the deaths of 464 people. People lost their homes, saw personal property damaged or suffered mental and physical health issues.

Three months into 2024, we’re staring down the barrel of another potentially record-setting hot year. If there’s a silver lining, it’s that the US is now better prepared than ever and we know what steps you can take to better deal with these unwelcome events. When it comes to weather, forewarned is forearmed. 

The US has been taking active steps. The Biden administration has provided funding to build resilient communities, and a new (as of September 2023) National Climate Resilience Framework, which should provide the US with a whole range of protections. These include conserving water resources, modernizing and strengthening the electric grid against weather and disasters and building infrastructure to protect communities and ecosystems from sea level rise, tidal flooding, hurricanes and storm surges.

At home and in your community, you can take steps, too, including preparing your home for wildfires and flooding and recognizing signs of heat-related health issues. This way, when wild weather comes calling, its impact on our homes, health and livelihoods is minimized.

Forecast 2024

Last year’s heat was no anomaly. It’s part of a long-term trend: The last 10 years have been the 10 warmest on record, according to NASA, with most of the Earth’s warming taking place over the last 40 years. Most forecasters are anticipating yet another year of extreme heat ahead.

«If we look at the forecast for the next three months in the long range, it’s suggesting that the trend that we’re seeing in baseline warming could continue, and so 2024 could rival 2023 for being the hottest year on record, which is very scary,» says Chloe Brimicombe, a heatwave researcher at the University of Graz.

Some of the extreme weather we experienced in the latter half of last year and will continue to experience in the first half of this year is a result of El Niño, a cyclical climate event that sees unusually warm ocean waters that has a knock-on effect of warmer temperatures and increased rainfall across the southern part of the US. For instance, temperatures in Death Valley, California, peaked at 128 degrees Fahrenheit in July, while forecasters predicted warmer temperatures in northern parts of the US stretching into February and a colder, wetter winter for Southern states.

While meteorologists are able to make long-term predictions about El Niño, other climate-related predictions are trickier. «All things told, we’re going to see an increased prevalence of heat events across the globe, but we can’t tell right now exactly where that will be,» says Andy Hoell, a climate scientist at NOAA.

What we do know, he adds, is that the climate crisis can compound events such as extreme heat or extreme rainfall to make them more likely or more severe. 

In the past, it wasn’t always easy to draw direct links between extreme weather events and climate change. But huge improvements in attribution science (the ability to specifically identify emissions as the cause for unusually dramatic weather) in recent years have changed the game. The World Weather Attribution program, based at Imperial College London, has now completed nine studies on droughts, heatwaves, wildfires and heavy rainfall in North America. «Every study found that climate change made the event more intense and more likely,» says Ben Clarke, a researcher at WWA.

The speed at which climate scientists are able to identify human-caused climate change as the culprit for extreme weather has also dramatically improved. Last year alone, Climate Central was able to attribute record-breaking spring heat in the western US, and ongoing extreme heat stretching through the summer in Texas and Florida, to climate change as it was happening. «It’s much more impactful as far as our understanding of what climate change really is if we can make that connection in real time,» says Andrew Pershing, vice president of science at Climate Central, a climate science analysis non-profit.

Thanks to attribution science, we can confidently point to a heatwave we’ve experienced and say whether climate change played a role in making it happen. But it also helps us to recognize that extreme weather events we’re experiencing are part of a pattern – one that can’t be broken without tackling the root causes of the climate crisis. «Until the world moves away from fossil fuels and reduces emissions to net zero,» says Clarke, «extreme weather events in North America will continue to become more intense, more dangerous and more deadly.»

Even if you live in a region that hasn’t yet directly been impacted by a climate-linked weather event, you’re not off the hook.

«As the climate continues to warm, most areas will be at an increased risk of some types of climate-linked extreme weather,» says Russell Vose, chief of the Monitoring and Assessment Branch at NOAA’ National Centers for Environmental Information and one of the NCA’s authors. «Perhaps the best example is extreme heat – it can occur anywhere.»

He points to the scorching heat dome that descended on the Pacific Northwest in June and July 2021, which was unprecedented in the historical record. The unpredictable nature of such extreme heat means no regions are marked as safe.

In fact, a region that’s been lucky enough to not yet experience an extreme heat event is more likely to experience one in the future and suffer more greatly due to lack of preparedness, according to a study published by scientists from Bristol University last April.

Scientists are more concerned about the ability of people in areas that don’t usually get intensely hot to cope when their turn comes. «What worries me would be something in the Upper Midwest or the Northeast that just hasn’t had a major heat event for a few years,» says Pershing. «I think we kind of lose a little bit of that muscle memory.»

Weather’s unequal impacts

The weather might not discriminate when it comes to who gets hit, but that doesn’t mean its impacts are experienced equally by all groups across American society.

«Certain groups are simply more vulnerable to extreme events due to geographic, socioeconomic or demographic factors,» says Vose. He points to the extreme rainfall brought by Hurricane Harvey in 2017, which led to a large number of homes being flooded in Harris County, Texas, with a disproportionate impact on low-income Hispanic neighborhoods.

When a heatwave hits, it will feel hotter in high-density urban environments that are more likely to be occupied by people of color or people living in poverty than in more spread-out neighborhoods or rural areas. Then some are homeless and can’t access health care. They have little ability to protect themselves, no matter how much warning they get about an incoming heatwave. This makes these groups much more vulnerable to the health risks of extreme heat.

Heat researchers are extremely concerned about people who live in housing not resistant to warm temperatures, says Brimicombe, who points out that those who rent are especially at risk. «If you’re a tenant, you have less ability to adapt your house to extreme heat than if you’re a homeowner,» she says. «And that also means young families, because babies are vulnerable to extreme heat.»

Not only are economically disadvantaged communities in the US more susceptible to feeling the worst impacts of extreme weather, but they have also done the least to contribute towards the climate crisis in the first place. A study published last August revealed that the wealthiest households in the US are historically responsible for 40% of the country’s climate emissions.

Meanwhile, these same households have more tools at their disposal to protect themselves from the impact of climate-related weather events. In 2019, The New York Times reported that wealthy California residents were banding together to hire private firefighters to protect them from the impacts of wildfires.

The Biden administration is well aware that marginalized and minority groups are hardest hit by climate change, including extreme weather. At the beginning of his term, the president set up the White House Environmental Justice Advisory Council, made up of leading experts from the US climate justice community.

Last September the group published its policy recommendations urging the government to ensure climate disasters do not further or exacerbate harm to vulnerable populations and communities. 

«Disaster relief should never be the cause of deepening inequality in any neighborhood, region, or Tribal community,» the council wrote in its recommendations. «When disaster hits, the goal of government should be that the people hit the hardest should emerge stronger and more secure than before, not the opposite.»

It recommended a number of measures that would help protect people in case of extreme weather including the creation of a low-cost national flood insurance and the establishment of a «Just Relocation Fund» that would provide communities hit by climate impacts with a relocation process based on a dignity framework with respect for their human rights. 

The White House has yet to respond to the recommendations, but if it does act on them this would hopefully prevent a repeat of the aftermath of Hurricane Katrina in 2005, in which Black communities were allocated less money to rebuild their housing, resulting in a lawsuit against the federal government.

Through the Bipartisan Infrastructure Law and other initiatives, the Biden administration is investing heavily in adaptation, mitigation and resilience measures designed to protect all Americans from the impacts of climate-linked extreme weather. As with all funding, people may have to wait some time to feel the full impact of that funding. In the meantime, there are a number of steps you can take to keep yourself safe in the months ahead.

How to weather the weather, whatever the weather

Summer’s not so far off, meaning sizzling days are on the horizon. 

Intense heat poses some scary risks to our health, including heat cramps, heat exhaustion and heat stroke, which can be life-threatening. It’s important to familiarize yourself with the signs so that you’ll recognize them in yourself and others, and can therefore seek medical attention if necessary.

Remember that heat is more likely to adversely affect older people, children and babies, and those with preexisting health conditions. There may be cooling centers or other well-air-conditioned places in your community where you can take refuge – if you do, consider taking elderly or vulnerable neighbors with you. «Look out for friends and families,» said Brimicombe. «Don’t be complacent.»

The British writer and fellwalker Alfred Wainwright is widely credited as coining the phrase, «there’s no such thing as bad weather, only unsuitable clothing.» Wainwright, who died in 1991, didn’t live through the kind of consistently bad weather we’re experiencing in this era of extreme heat, but that doesn’t mean we have nothing to learn from him. In the midst of a heatwave, it’s best to wear loose-fitting clothes in light colors, rather than black, which absorbs the heat.

Make sure you stay hydrated and try to spend as little time as possible outside in the sun. Try to block sunlight from warming your house, and consider buying reflectors to place in your windows that can help keep the heat out. At nighttime, take note of when it might be cooler outside than in, and use this to your advantage by opening doors and windows to let the internal temperature of your house regulate. Fans can be effective, but at very high temperatures they’re likely to just start pushing the hot air around – in which case you should, sparingly and without putting too much pressure on the grid, resort to air conditioning, or moving to your local cooling center.

Remember that global warming is worldwide, so the same heat warnings apply even if you plan to travel to other parts of the world over the summer. The heat waves that hit the US in the summer of 2023 also impacted areas of Europe, including popular vacation spots in the Mediterranean. Countries including Greece, Spain and Italy were all affected by wildfires that resulted in the evacuation of locals and tourists alike from some areas and islands.

The surge in Europe-bound American tourists that occurred in 2023 is expected to continue this year, but if you’re planning to be among them it’s important not to travel without comprehensive insurance. Likewise, if you’re traveling in the peak months of July and August, be prepared to adjust your itinerary in case of extreme heat to ensure you’re not putting your health at risk. This may mean spending more time indoors than you’d planned for the sake of your health.

For other types of extreme weather that may hit your property such as wildfires, storms or floods, it may be useful to have an evacuation plan. You should prepare an emergency evacuation bag, also known as a go bag or a bug-out bag. Don’t forget to plan for your pets. The National Fire Protection Association has a handy guide on how to prepare your home for wildfires

One of the easiest but most important things you can do is keep an eye on long- and short-term weather forecasts. The silver lining for people in the US, says Pershing, is that the country has great weather forecasting capabilities and the channels to communicate incoming events to people so you can prepare. «The gaps are really whether you take it seriously yourself,» he says.

So for anyone who does take it seriously, be sure to read our tips on how to prepare yourself and your home for wildfires, hurricanes, floods and storms.
