COMMENTS:
Saw Lacrosse 5 (visually) flare to mag 1 at 2:55:30 +/- 30s 9/16 UT in
Cygnus. Did not record the pass as I didn't think it would be dark enough,
but it was.. I was only looking to see if I could spot it at all.

AEHF1 is an easy target. Mag 9 near shadow entry and shadow entry was a few
minutes early from the Heavensat prediction. The last point is exactly where
ObsReduce says shadow entry would be, but I saw it a couple minutes past
there.

Prowler is not easy, but it is never the same magnitude twice. It usually
disappears just before an easy to spot "flash", but did not do this last
night. Only one flash early on.

Vortex 2 has a distinct heartbeat of 5 to 10 seconds.. Could post a short
video if anyone wants to see it..

Caught Vanguard 2 pass quite near to AEHF1. First sat I have ever seen that
is older than me.
