[amsat-bb] Re: AO-27 Scheduler

[George Henry]

That's due to normal precession...  over time, the ground track moves eastward, 
causing the workable passes to occur about 28 minutes earlier each day.  You'll 
soon see workable passes in the evening, which will work their way into the 
afternoon as they get earlier, day by day.

What goes around, comes around.
