Can anyone tell me what the moving object is in the little red box in this animation of Comet 132P/Helin-Roman-Alu 2?

It looks like an asteroid. As I haven't got a time I can't really check. Goto to MPC and check yourself with the actual date and time:

Will do. Thanks for pointing to this link!

Hi Rob,

I just made some checks with ASTAP which can automatically detect and identify objects not contained in start DB. The object was clearly identified as not in DB (though I had only very poor quality pulling the coarse data from the gif and got some false positive), but since I have no precise time and observing location an automatic identification is not possible.
But you can try it out with one of your original images and precise data. It should be easy to identify.

Thanks. I’ll download the software and give it a shot after the Michigan game with the original subs.

It's always a good idea to try ASTAP for identifying asteroids.
It will use time and location ( if given in the TIFF header) to identify all asteroids in the MPC data.

Best regards

Based on MPChecker, it might well be the asteroid (877) Walküre. While 132P/Helin-Roman-Alu  was at:  00 41 46.7 -02 51 46 ,   (877) Walküre  was at:  00 41 23.2 -02 42 56.

Just after you posted this I saw that on ASTAP. Never knew about this program so I appreciate everyone's help here. Always learning. (I had flipped the images for a better look)

Thanks for the feedback! That is science as science could be - a theory followed by proof of evidence. smile
Yes, ASTAP is an excellent tool. One of the fastest universal plate solvers and contains tons of helpful tools. It is actively developed. Almost every day a new version with new cool functions. And the best: It is for free.

I just installed ASTAP and used it on some frames I took of 67P/Churyumov–Gerasimenko ... worked fine ... and found out that (281) Lucretia was on the same frames!  Thanks again @Ruediger for your help and @Rob Calfee for triggering this with your question!
