Re: [Comet-Images] Re: What is this?

1. I doubt it is an internal refl;ection. I've never seen a reflection having
the appearance thee shown.
2. A check of the MPC checker (checking some 415000 objects) shows nothing
within the region.
3. On close inspection of the image, I have severe reservations about whether
what you have identified is a moving object. It
looks more like two close stars with background noise. As with any moving
object, two images should be take, to establish
movement.

Finally in situations like this. To make it easier for others to follow up (and
not waste their time), you should:
1 specify the date time of the image in UTC. Don't assume that people know what
the time zone correction is for your location. I
had to guess;
2. you should estimate the object's location. Tools like GoogleSky should make
it easy for you to estimate the RA and Dec.
3. Of course, if you have the UTC and approximate RA and Dec, you can then do
your own check against the MPC Minor Planet Checker.
