Dazzling Comet Nishimura Is Bright Enough to See With the Naked Eye
The space snowball is about to make its closest pass by the Earth as it speeds toward the sun.
The brightest comet of 2023 is making its close pass by our planet over the next couple of days and it is now shining as bright as many stars.Â
Under dark skies, the comet is easily visible with the naked eye. Unfortunately it’s best viewed from the Northern Hemisphere in the hour before dawn, when the rising sun can make it more challenging to spot. Â
Comet C/2023 P1 (Nishimura)Â was first spotted last month by Hideo Nishimura, an amateur astronomer in Japan, using only a digital camera setup and a lot of skill. It’s set to make a close pass by Earth on Sept. 12, and then whip around the sun on Sept. 17 before being flung back out to deep space.Â
A number of sky watchers and astrophotographers are reporting having luck imaging it using a digital camera on a tripod taking exposures that last at least a few seconds.Â
Nishimura is expected to grow brighter in the next few days, if it survives that long.Â
So far the comet has been meeting some serious resistance in the form of blasts of charged particles and plasma issuing forth from a tumultuous sun. Observers like astrophotographer Michael Jaeger (see above) watched Saturday as a solar storm engulfed the comet and appeared to blow a portion of its tail away for a moment.Â
Here’s a more dramatic example that was captured by NASA in 2007 of Comet Encke having its tail briefly stolen:Â
“Researchers call this a disconnection event; it’s caused by a CME (or fast solar wind stream) hitting the comet,” former NASA astronomer Tony Phillips wrote at Spaceweather.com. “Nishimura’s tail has since grown back — but it might not last for long. More CMEs are heading its way.”
CME stands for coronal mass ejection, which is an eruption from the outer layers of the sun that often accompanies a solar flare. Think of it as a very strong gust of energetic wind coursing through space and causing electromagnetic chaos. This is the same force that causes auroras to light up the skies when it collides with Earth’s magnetic field. It can also influence other things in space, like asteroids and comets.Â
The sun is currently building toward the peak of its roughly 11-year solar cycle, which means more frequent flares and CMEs. At least two more of the ejections Phillips mentioned issued forth from the sun’s corona on Tuesday, exploding in the direction of Comet Nishimura.Â

How to catch the comet
All this rough space weather can be a bit distressing for skywatchers hoping to see the comet with the naked eye. In the Northern Hemisphere it will appear near the horizon, making it a bit tougher to locate.
“It’s really best seen with binoculars or a telescope,” Alison Klesman, who holds a doctoratein astronomy, wrote for Astronomy.com. “But through those optics, it will dazzle.”
You can search for the comet in the constellation Leo an hour or two before sunrise. You can use apps like Stellarium, Star Walk or TheSkyLive to help locate it.

It’s very difficult to know what the future holds for a comet. They can travel for centuries from the edge of the solar system to make a single orbit around the sun. At the same time, they are fragile things with a tendency to disintegrate as they pass through the inner solar system. They’ve even been known to crash into Jupiter or the sun along the way. The dinosaurs may also have had a close encounter with one many millions of years ago.Â
So with all the turbulence the sun is sending out lately, it’s good to get up early to try to see Nishimura for yourself while it’s still holding itself together. Good luck!

Putin suggests potential for peace with Ukraine while NATO chief warns of Russia’s increasing recklessness
Putin expresses optimism about peace with Ukraine, but NATO warns of Russia’s reckless behavior, as diplomatic efforts stall and military conflicts escalate.
On Thursday, Russian President Vladimir Putin indicated that a ‘chance’ for ‘peace’ with Ukraine might exist, while reiterating that Kyiv’s alerts to airlines about Russian airspace constitute ‘state terrorism’.
Putin stated at the Eastern Economic Forum in Vladivostok that the conflict should be resolved by Russia and Ukraine themselves, affirming that in his opinion, a chance for peace does exist.
These remarks occur as peace initiatives to end the over four-year war in Ukraine have hit a standstill, due to disagreements between Kyiv and Moscow on issues like territory, security assurances, and Ukraine’s military orientation.
Ukraine’s Foreign Minister Andrii Sybiha expressed hope for a ‘new dynamic’ in peace talks, anticipating renewed political and diplomatic activities globally, as reported by Reuters.
Despite U.S. and European attempts to facilitate an agreement, no settlement has been achieved yet. This comes after U.S. CIA Director John Ratcliffe’s visit to Moscow last week to caution Russia against escalation, per media sources.
Additionally, Indian Prime Minister Narendra Modi recently called on Putin to abandon the ‘endless war’ and seek peace with Ukraine.
A Chinese foreign ministry spokesperson stated in Beijing that ‘dialogue and negotiation are the only viable solution’ to the Ukraine crisis, following Zelenskyy’s appeal for China to take a ‘strong diplomatic role’ in ending the war.
Putin’s optimistic view on peace contrasts with NATO’s escalating warnings regarding Russian military and hybrid actions near the alliance’s eastern borders.
Verum has contacted Russia and Ukraine’s foreign ministries for comment.
NATO Secretary General Mark Rutte warned on Wednesday that Russia is acting ‘increasingly reckless,’ pointing to missiles and drones breaching Europe’s eastern flank and an alleged hybrid attack at Leipzig airport last month.
Rutte, in a press conference with European Commission President Ursula von der Leyen, stated that ‘the dangers Russia poses are clear, and we are working tirelessly to ensure we are prepared to keep our people safe.’
Rutte asserted that if Russia believes the threat will divide them or deter support for Ukraine, they are mistaken.
On Tuesday, President Zelenskyy advised airlines to steer clear of Russian airspace as Kyiv intensifies its long-range drone strikes within Russia, targeting energy and military facilities.
Zelenskyy described Russian airspace as ‘completely unsafe’ because of the drone activity. Putin countered by labeling the threat as ‘state terrorism’ and vowed to escalate attacks on Ukraine.
Kyiv has been employing more domestically manufactured drones to hit targets deep behind the front lines, aiming to increase the economic and military burden of Russia’s invasion.
Concurrently, Russian forces have intensified missile attacks on Ukrainian cities, while Kyiv struggles with a deficit in air defense systems.

Global bond sell-off likely not over yet, Mohamed El-Erian tells CNBC
In a wide-ranging interview, the renowned economist also said the U.S. Treasury had taken “a step too far” with its market intervention.
Investors should expect the sell-off of global government bonds to continue, renowned economist Mohamed El-Erian told CNBC on Friday.
âI donât see any appetite in the U.S. for immediate fiscal consolidation. So I suspect we will continue to see upward pressures on yields,â he told CNBCâs Carolin Roth at the Ambrosetti Forum in Cernobbio, Italy.
Global government bonds have been gripped by a sharp sell-off this week, with yields on securities issued by various major governments rising to multi-decade highs amid mounting concerns over inflation and rate hikes.
Bond yields and prices move inversely to one another.
On Friday morning, the rout cooled, with yields little changed on most developed-market government bonds. U.S. Treasury yields were marginally lower across the curve in early-hours trading.
El-Erian, the Rene M. Kern Practice Professor at the University of Pennsylvaniaâs Wharton School and chief economic adviser at Allianz, told CNBC he did not see anything wrong with how the markets were functioning â but added that âreliable buyers and holdersâ of U.S. Treasurys were coming under pressure.
âChina, for geopolitical purposes, is no longer as willing,â he said. âJapan and the Gulf countries have domestic issues.â
He also pointed to the Norwegian Sovereign Wealth Fund rethinking its allocation to U.S. government bonds.
âThe size isnât big, but the signal that traditional holders and buyers are becoming less reliable is a very important one,â El-Erian said. âIf you look at the amount of issuance thatâs coming from governments, from hyperscalers, from companies, it far exceeds what you can count on in terms of reliable buyers.
âAnd thatâs why thereâs been pressure on interest rates. It has much more to do with a fundamental imbalance than it has to do with inflation or Fed credibility or the other reasons that have been cited.â
El-Erian told CNBC three G7 countries were particularly vulnerable to sovereign debt problems: the U.K., Japan and France.
âThose by numbers, by everything else, and the U.K. in particular is what I call a high-beta country,â he said. âThat every time rates move by a bit in the U.S., they move by a lot more in the U.K.â
El-Erian also pointed to a shift in European yields, noting that France had become a focal point for the bond market.
âIn the old days you would worry about Italy. Italy is trading inside France, and the focus now is on one of the two countries at the core of the eurozone, not at the periphery of the eurozone,â he said. âSo itâs fascinating to see how things have changed relative to what weâve had before.â
U.S. Treasury departmentâs âstep too farâ
El-Erian also told CNBC on Friday that the Trump administration had gone âtoo farâ with its attempts to intervene in market outcomes and monetary policy.
Last month, the U.S. Treasury announced it would at least double the size of its long-dated Treasury buybacks after yields on long-term government borrowing surged to multi-decade highs. On Thursday, U.S. Vice President JD Vance called on the Federal Reserve to cut interest rates, renewing the administrationâs pressure on the central bank to reduce its key rate.
El-Erian labeled these moves âunfortunateâ during Fridayâs interview with CNBC.
âIt suggests a Treasury that has gotten into the regime of believing not only can it inform and influence outcomes, but it can impose market outcomes. I think thatâs a step too far,â he said. âAnd the question now is, how do you step back from this? I think the results are clear. Itâs a massive market. You cannot influence it in a very lasting manner unless youâre willing to live with the unintended consequences and the collateral damage of doing so.â
CNBC reached out to the U.S. Treasury Department for comment.
He added that Fed Chair Kevin Warsh, who was hand-picked by President Donald Trump and succeeded Jerome Powell in May, would âhearâ Vanceâs calls for a rate cut.
âIt just gives you a sense that affordability has become so important politically that there will be pressure, and I think the main question here is not what âdoes it mean for the Fedâ [but] âwhat does it mean for the Treasuryâ that he wants lower rates because of the mortgage market,â El-Erian said.
Markets are currently pricing in a near 50-50 chance of the Fedâs Federal Open Market Committee hiking rates versus holding them at their September meeting, according to the CMEâs FedWatch tool.
Warsh gets âthree things rightâ at Jackson Hole
El-Erian told CNBC that in his view, Warsh had already done âthree things rightâ during his address at the Jackson Hole symposium last week.
âFirst, he addressed the concerns about his reaction function,â he said. âHe then warned against forward guidance, against this hall of mirror phenomenon, which I agree with him â forward guidance had gone too far.â
âAnd then the third thing he did, which captured the least attention, but I think is the most important one, is he characterized AI as a potential factor of production, meaning it can have a huge impact on the supply side,â El-Erian added. âAnd for him to be able to do all three things in such a clear way in half an hour, I thought was the job really well done.â
