Comet Nishimura photographed on Aug. 19, 2023, by astrophotographer Dan Bartlett. -
Tangentially related to this CME event caught by PSP is this fascinating video of comet C/2023 P1 (Nishimura) taken by the STEREO-A solar observatory during Sep 17-24, 2023.
The movie shows the comet's ion tail interacting with the solar wind. There was a glancing blow from a coronal mass ejection (CME) during the Sept 22-23 timeframe!

Comet #Nishimura in STEREO's field of view, now in full resolution and with a lot of detail in the tail: from the animation http://nickdjames.com/STEREO/20230918.gif described in https://groups.io/g/comets-ml/message/31691

A ground-based view of #Nishimura for a change - the comet yesterday at dusk, a mere 1.3° above the horizon, shot by Gerald Rhemann remotely in Namibia: https://www.facebook.com/photo/?fbid=6311705662289786 (all viewing windows for Central Europe have closed; Nish has turned into an equatorial / Southern hemisphere object now but the elongation remains poor - it was only 13.5° here).

A familiar sight by now ... #Nishimura at 1:17 UTC in the first STEREO beacon picture of today: https://stereo-ssc.nascom.nasa.gov/browse/2023/09/21/ahead/hi1/1024/ (very few new groundbased images around, like https://spaceweathergallery2.com/indiv_upload.php?upload_id=199948 from Sep. 20, https://britastro.org/observations/observation.php?id=20230919_224751_e05f2919b950fde2 from Sep. 19 and https://twitter.com/jperez1690/status/1704533911119011919 from Sep. 18).

The latest #Nishimura beacon image from STEREO, taken at 3:17 UTC today (20 September) - refresh https://stereo-ssc.nascom.nasa.gov/browse/2023/09/20/ahead/hi1/1024/ every few hours for future pictures: there is quite some (low surface brightness) tail trailing the comet. The full-resolution images will sure be something ...

Comet #Nishimura as seen by STEREO at 11:17 UTC on 19 September, one of four preview images available from that day on https://stereo-ssc.nascom.nasa.gov/browse/2023/09/19/ahead/hi1/1024/. The comet's brightness is roughly +2.5 mag. right now: https://groups.io/g/comets-ml/message/31683. And an animation of it moving into the field of view: https://www.facebook.com/watch/?v=275340641977067

By far the best deep-in-twilight-at-dusk image of comet #Nishimura I've seen so far just dropped at https://spaceweathergallery2.com/indiv_upload.php?upload_id=199817 (taken on La Palma at 2.1 km altitude). Meanwhile I've summed up the 'evening' sky / perihelion experiemce with Nish in https://skyweek.wordpress.com/2023/09/19/allgemeines-live-blog-ab-dem-19-9-2023/#Sep19 - the comet behaved as normal as one could imagine, no fizzling in the Sun's heat, no outburst either, just doing what I predicted 3 weeks ago in https://skyweek.wordpress.com/2023/08/28/deutscher-fahrplan-fur-c-2023-p1-nishimura/ i.e. getting ~100 times brighter over that interval. ;-)

Not the best but by far the "fattest" image of #comet #Nishimura these days, in a preview image from a camera on the #STEREO A spacecraft taken at 15:17 UTC today: find the latest such "beacon" pictures at https://stereo-ssc.nascom.nasa.gov/browse/2023/09/18/ahead/hi1/1024/ (and see https://twitter.com/halley_7898/status/1703758728246513986 and https://twitter.com/kumagayakimura/status/1703769391957975239 and https://twitter.com/sqm18astro/status/1703366962485793216 and https://twitter.com/kumagayakimura/status/1703771976748417324 for some ground-based detections at dusk today from Japan and https://www.facebook.com/photo/?fbid=849002330164280 and https://twitter.com/kumagayakimura/status/1703438723256562132 for dusk pictures from yesterday).

Whoa - easily the best image of #comet #Nishimura in the kinda-evening sky I've seen so far, taken only hours from #perihelion: "2023 sep. 16 18.00 UT 40x1 sec 30x0,5-0,8sec Leica-Apo-Telyt 280/4.0 Nikon Z6mod Michael Jäger" (original caption). No outburst of brightness thus (well, hoping for one had been a longshot anyway) but also no heat damage, let alone destruction, to the nucleus. Sadly in 3 days the comet is (orbit-wise) history for Europe anyway. And won't be better further south either.

Vanochtend de wekker trouwens vroeger gezet in een poging de komeet Nishimura te zien. Alsnog te laat. Maar als het goed is hebben we dit weekend nog een paar kansen. En heldere nachten 🤞
Een komeet, mensen! Die pas over 400 jaar weer passeert! Gaat dat zien ☄️https://www.nationalgeographic.nl/wetenschap/a45101058/groene-nishimura-komeet

Newly discovered green comet Is passing by Earth this week.
Smithsonian Magazine reports: "Comet Nishimura, which appears only once every 435 years, is on track to approach the sun and shoot into deep space."

I've not managed to get a look at #CometNishimura. Does anyone have photos to share?

Comet #nishimura last Friday morning around 4:30 from northern Germany. #astrodon

As always it is unfortunate and plainly misleading how photographic images of comet C/2023 P1 (Nishimura) imply an easy to see naked eye comet with a long tail. It is not.
I can understand that not every photographer adds this explanation to their images but I have now seen so many click-bait websites praising this comet as something for the layman. Not nice. #comet #nishimura -
Comet C/2023 P1 (Nishimura) over Stonehenge!

Here is another outstanding image of comet C/2023 P1 (Nishimura), this one taken by Sławomir Matz.
His post reads - "C/2023 P1 (Nishimura) photographed on September 7, 2023. The comet is currently popular in the media and can be visible to the naked eye. I wrote about her on Facebook! Look for the peja "Stars in the hands."

The light curve below shows that comet C/2023 P1 (Nishimura) is brightening up nicely. Current apparent magnitude is below 4 (lower is brighter).
In theory, objects with mag 6 and lower are visible to the naked eye, but currently the comet is low on the horizon during the early morning hours, so visibility depends on local conditions. Binoculars help.
After Sep 17, it will be too close to setting sun as seen from the northern hemisphere.

Some beautiful images of comet C/2023 P1 (Nishimura) are getting posted online by amateur and professional astro-photographers, as the comet nears its closest approach to earth on Sep 12.
Let's take a look at a few.
This first one, posted on apod, was taken in eastern Slovakia by Petr Horálek / Institute of Physics in Opava.
Check out this earlier thread for some more info on the comet - https://fosstodon.org/@AkaSci/111008086190146961

Do Look Up:
Astronomy aficionados are buzzing about a bright new comet.
The ball of dust and ice is formally named C/2023 P1, but is also called #Comet #Nishimura, for Hideo Nishimura, the Japanese photographer who first spotted it on August 12.
You may have an opportunity to see it as well during the early morning.

#DidYouKnow: Comet #Nishimura (C/2023 P1), Named for Hideo Nishimura, the Japanese photographer who first spotted it, may be visible now.
Nishimura captured the comet on Aug. 12 while imaging the sky before sunrise with a digital camera — the third comet he has discovered.

An welchem Starlink Satelliten muss ich denn vorbeilinsen, um #Nishimura zu sehen?
