I took about an hour of data on NGC 3628 tonight March 5th, around 1AM EDT. In processing the images I noticed a "moving star" which I have to assume is either an asteroid or some other space debris. It's moving about half an inch over the whole hour. So whatever it is, is much slower than what I am used to seeing with LEO satellites. I poked around in Stellarium and got nothing. Then I discovered the small body identification website hosted by JPL. I'm not sure if I am looking at the results right or using the website correctly, but the JPL website comes back with two possibilities. I'm curious on how to go about validating that one of these is indeed the object in question.

498 Tokio                12:08:14.05 +13 28'28.3"   3.E3 -1.71 4.2E4  13.7

1062 Ljuba               10:00:42.60 +13 27'31.3"  -5.E3 -58.7 7.3E4  14.1

Could it be 9262 Bordovitsyna? The minor planet center data shows it in this area.

Yes it's brightest in the area - mag 16.6.

(9262) Bordovitsyna    11 20 27.5 +13 42 29

 

How long were these exposures ?

Did you update Stellarium asteroid data ?

Exposures are 2 minutes using an AT8RC on an ASI1600 with no filters. I should update my signature.

ASTAP can mark asteroids on an image (see https://www.hnsky.or...roid_annotation). Also see a recent thread on the same topic: https://www.cloudynights.com/topic/752726-how-to-identifyconfirmreport-a-possible-minor-planetary-object

I was using the JPL website incorrectly. I was able to understand that a little better tonight and it matches up with what was already identified earlier in the thread. I will have to take a look at the applications mentioned here.

With the correct parameters the JPL website comes back with the following. 
 

9262 Bordovitsyna        11:21:27.30 +13 35'39.9"   5.30  430. 437.2  16.6

My initial post is a region of the sky off the back end of Leo, which is no where near close.

Thanks for the help.
