C/2023 P1 Nishimura
Bright (Naked-eye) comets are rare — the kind that can excite those of us without binoculars or telescopes — appear on average perhaps two or three times every 15 to 20 years. The last such comet to do that was comet NEOWISE (C/2020 F3) in July 2020.
I will share a couple of photos of Neowise at a later time.
Comet C/2023 P1 Nishimura (discovered in 2023 by Nishimura) More in-depth information here
Magnitude is the rating of Brightness, the lower the number the brighter - For example: The Sun=-27, Full Moon=-13, International Space Station=0-3.9, Polaris=2, Andromeda=3.4
September 5: C/2023 P1 (mag 5.6, elongation 27.7°) enters the constellation Leo.
September 6: C/2023 P1 (mag 5.3, elongation 26.3°) passes 0°6' away from the star Ras Elased Australis (mag 2.95) in the constellation Leo.
September 9: C/2023 P1 (mag 4.4, elongation 21.2°) passes 0°33' away from the star Adhafera (mag 3.4) in the constellation Leo. Approximately the same Brightness as Venus

The 7th is busted, it showed clear skies couple of days ago. Hoping things don't change for the 8th and 9th.

Note that light spillage is noticeable by 4am, and the sky might get some color by 6am. Depending on how bright the comet is in comparison to local conditions, this might not be a bad thing. If it is bright enough to have good contrast against the morning sky it would make for a good photo. In other words, in spite of all the predictions and preparations, you never know.

Although events near the horizon can be spoiled by light pollution, having astronomical events near the horizon is a good thing. It allows the inclusion of foreground landscape and interesting objects (man made or otherwise), to give the scene context, relevant to an event. You won't see me taking a closeup shot of the moon whether it be a super blue or whatever moon because the moon by itself could have been taken any time, from any place, even a hundred years ago. You can't even claim copy right to it because there are 100 billion same shots. If it happens high up in the sky, I am not interested. No context. NASA has better pictures.
I am not having high hopes on this one so I am staying local. Less prep and more sleep...
Comet of a decade' to whiz past Earth in likely first visit in 4.5 billion years
C/2023 A3 could be among the brightest in a decade when it visits next year. The comet is making its first visit since our inner solar system was created 4.5 billion years ago.
This is the one I am most looking forward to. I will travel for this one.
In early 2023, the ATLAS survey and Purple Mountain Observatory detected a comet that was named C/2023 A3 (Tsuchinshan-ATLAS). It is expected to reach naked-eye visibility by October 2024 and become as bright as the most luminous stars! Here is everything that is known about this comet so far.
