Drew, thanks. I am reading email in reverse order, so sorry
about not seeing this email first. Thanks. This gives the
needed bits to infer the "rule" that is driving the schedule.
1) ascending pass.
2) passing approximately 30 deg N latitude
Thanks! This is easy to see on any satellite tracking
I wonder if it could be added to the AO-27 web page...
