Thanks, Rainer, according to the MPEC ephemeris, giving mag. 16.0 at 1 million km, the standard magnitude should be near +1.0 ! Using JPL geocentric ephemeris, I created a SkyMap .trj file Set main menu option F5 Plot mode: Rocket Trajectory F3/F1 Map date: 2007/11/13 F2 Map time: 19:00:00 F4 Date/time type: UTC F7/F6 Rocket standard magnitude: 1.0 and F7/F1 to the file containing the data at the end of this message (+ of course your site coordinates on F2) ----- Original Message ----- ...> > As you may know, ESA's comet
