Hi, Thanks to Ed light, Jason Hatton, Michel Jaquesson and Leo Barhost on their posts. Ed provided a skymap .cfg file that gave the correct trajectory, but I had problems trying to duplicate it. I finally corrected my errors and was able to reproduce the trajectory. It is highly likely that the obs was of 81119B as the trajectory and photometric period match (are very close to matching).
