About a month ago the events that turn AO-27 on and off seemed to be
timed so it would be on as it passed over North America. More
recently, for the passes I check (more than 10 degrees here in NC),
it seems like according to schedule on www.ao27.org, the "ON" time is
when the bird has pretty much finished its pass.
For example, right now at 1858, the footprint of AO-27 neatly covers
much of the US and Canada, yet according to the website the next "ON"
event is at 1906, one minute before I lose the satellite completely.
Is this intentional or "just the way it is?" Does it slowly cycle the
ON time so it is ON for passes in different parts of the world?
