I just added another six asteroids that I identified in my Asteroid Ulysseus image and uploaded the new image, replacing the original. I haven't looked to see if they are duplicated in others' observations. Not sure how you like to do the book keeping.

I'll add your additional observations to the list. I am keeping duplicates though as to list all observations. The table can be further filtered to make a unique list.

I went back to my original Patroclus image to see if I could possibly identify any more asteroids and found a few more using the MPCORB database. The position, relative length and orientation of proper motion, and brightness seemed consistent with the database for identification.

A (617) Patroclus mag 16.1
B (13293) Mechelen mag 18.7
C (11845) 1987RZ mag 19.1
D (91358) 1999 JL65 mag 18.9

I uploaded a revised image with labeling.

Many thanks! I have now added your new identifications to the list.
