Hi Patrick, I set this up as instructed. One thing I was tempted to do was to change the Ephemeris Generator time output to UT-5 (I'm in NJ, USA). Wrong. If I do this Rosetta doesn't even show up. I just have to assume CDC is compensating for UT is all and I believe it is. The start of the action (for me) is in Gemini at 21:50 EST (10 PM). After that for about 10 minutes it really starts to book towards the horizon. I wonder what magnitude it will be during this part? Strictly binocs? ------------------------ Yahoo!
