I leave tomorrow afternoon (June 16th) so I'll try to figure out the time and have a look. Right now we are on PDT. PST is an hour earlier so taking that into account, and swapping back from a 24 hour clock, gives me the times in green inserted into your info.
"06-18 2010 16:48h PST (3:48 PM)
144degrees True azimuth, 30 degrees elevation.
06-18 2010 17:51h PST (4:51 PM)
162degrees True azimuth, 34 degrees elevation.
Earlier time is when the elevation matches the elevation of the sat - later time, azimuth matches but elevation is 3 to 4 degrees high.
6-19 2010 18:34h PST (5:34 PM)
162degrees True azimuth, 28 degrees elevation. If you see that one, you've got it for sure - azimuth correct, elevation 2 to 3 degrees low."
Does that look like what you expected? Thanks for the assist.
