Tonight in S CA there are 3 Iridium flares predicted in 2 minutes, at
least in my location. Naturally 2 are not in normal status; they're
marked with ?.

I guess we might see something ... good chance for a photo? The sky may
be a bit bright though with the sun at only -7 degrees ... if the sky
were darker CCD owners could go over the top by adding a few pictures.

Iridium 20A seems to have had an orbit change recently; predictions I
made 9 days ago with then-current TLEs are now incorrect by 1 minute
using the latest TLEs.

Here is the raw Skymap output:
