My mistake was looking for the pass
using the graphical plot from SatSpy. I'm not
sure how the program handles this type of pass--the ephemeris, listing RA
and Dec, matched but the graphical plot was way off.

I have also recently had trouble using SatSpy for distant/long duration
passes. Last night I tried looking at two rockets out of current eccen.tle
as they passed north through Bootes at about 10th magnitude (I was using
my 10" reflector, these should have been easy). I saw neither satellite
pass along the track in the graphical display, and later noticed that the
ephemerides were more or less parallel but 5-10 degrees west. I also used
SatSpy to locate Superbird A in Hydra for its 03:33 UT peak; the
ephemerides had it nearly 120 DEGREES TO THE WEST! (RA 0h 9m 35s) while
the graphical display looked about right (I did manage to see Superbird
A's flashes = cool!).
	Does anyone know what is going on? I have contacted with the details late last night but have not heard
back yet.
