Comt 246P/NEAT 2020-Feb-02 10:47:54 UTC
has returned to the eastern morning sky in Virgo. It has its typical short dust tail and looks much the same as it did during the previous return.

Amazing
Very stellar appearance.
Brian Skiff noted stellar appearance in his Lowell Obs images a day later on 2020 Feb 3.1 UT
J. F. Soulier posted a new image/obs also shows stellar appearance lesia.obspm.fr/comets/lib/dis…

今朝(2日朝)のC/2020 A2 岩本彗星のスケッチです。
微光ながら、意外とあっさり見えてしまいました。付近の微星と比べると少なくとも11等はありそうです。
20cm62倍で、1.84UTにm1=10.9, DC=3-4, dia=2.0'と目測。
11等の新彗星。 - C/2020 A2 (Iwamoto) 岩本彗星 puzzlestar.net/comet/2020A2/2… pic.twitter.com/X85K9kOWum

NGC 7617 is labeled in your diagram
It is a galaxy in group of Galaxies
simbad.u-strasbg.fr/simbad/sim-id?…
N numbered annotations may be other ngc galaxies
Looks like they were measuring photographic magnitudes
There are quite a large number of galaxies nearby in the field.

Comet C/2019 Y1 (ATLAS) has brightened to 12th magnitude according to total magnitude reports from Steffen Fritsche, Carl Hergenrother, and Alan Hale over the past 2 weeks.

Hello, somehow I found your tweets and your website and it said to say hello.
It was the mention of Dirac
It seems like a dream now. I met him and conversed with him about quantum mechanics during a lecture he gave when I was a physics undergraduate around 1974.

it would be grand to see a sungrazer comet in the field of view of the PSP
that would blow us all away

Thanks for tip.
I deleted all the files under each folder in .astropy\cache
and will try this next time I get a problem.
>>> import astroquery
>>> print(astroquery.__version__)
0.4
pip install --no-cache-dir astroquery

for second time in last two weeks, astroquery started giving errors for code that worked previously although nothing had changed. Made no sense. but solved by
pip uninstall astroquery
pip install astroqery
it was same version. Nuts, something vewwy strange is going on
