Michael and I went west of town last night to get more pictures of the comet. The full moon was so bright that it washed everything out pretty quickly. It was tougher to see the comet, but it was still visible to the unaided eye. It looked very nice in 10x50 binoculars. #CometA3

@nearsys That’s M5 - a globular cluster in Serpens. Cool!

[Dr. Kendra Sibbernsen @ksibbern]

Looks like I got the anti-tail of the comet in this 2 minute shot on the SeeStar. That’s the faint line pointed toward the Sun when the tail it pointed away from the Sun.

[Dr. Kendra Sibbernsen @ksibbern]

Here are some photos that Michael took at Branched Oak Observatory last night of Comet C/2023 A3.

It should be visible to the unaided eye in the west after the sun goes down for the next week or so.

We were saying this is the best visible comet since Hale-Bopp (27 years ago).

Today, C/2023 A3’s coma, or body, has crossed out of SOHO’s field of view.

Tomorrow, it will appear in the night sky!

(Note: it appears to momentarily "slow down" here because the SOHO team increased the frame rate on Oct. 10th, taking more images in the same amount of time.)

@nearsys I love these lapidary posts!

@AllPlanets @Kickstarter @Unistellar @SETIInstitute Congratulations!

I’m watching the opening ceremonies too.

@AllPlanets I remember going to my first AAS conference as an undergraduate and seeing a poster predicting that Comet Shoemaker-Levy would hit Jupiter.

We viewed the impact sites with an 8” Dob from the top of the physics building. It was so much easier to see than anyone predicted.

@geophysichick @thegridkid Sad. Such a good word.

[Dr. Kendra Sibbernsen @ksibbern]

Amazing auroral activity even before the sun went down at Branched Oak Observatory in Nebraska.

It is a *mess* out there.

Michael and I were interviewed by an NPR reporter in St. Louis about the upcoming eclipse.
