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.
