Rob, Thanks, I reset the default mag for unknowns to the Molczan value and the predicted mag for the pass in question did come back at 4.3, with Coronas at predicted at 4.4, I would still say Coronas is dimmer than predicted though. An updated Satmag.dat file would be welcome, mine is dated 8/23/00. Two questions, can the Molczan data be downloaded from somewhere for updating purposes, and from where? Can the satmag.dat file be updated manually, ie using a text editor?
