Default Shuttle Pass at 5:50 AM

I just made a naked eye observation of ISS and Shuttle pass. My location is
in Southern California. ISS was steady, Atlantis "appeared" to be tumbling
with two regular flashes with a period of about a second.

What could cause this?

That's a really fast period for the Shuttle, must have been flashes from
reflections of the Sun off of bright surfaces. I'm looking forward to
seeing them tomorrow at 6:45, if they're still up there. 6:45 Central or
7:45 Eastern, would be the second landing opportunity. Maybe they'll get
an extra day onorbit. ;-)

Out of curiosity, how bright (qualitatively) is the shuttle compared
to the ISS? Was Soyuz visible as well, or has it docked?

The "flashing" that you saw was probably a result of the smoke that is
present in the atmosphere above Southern California from the wildfires
that have been burining in the area recently. I have noticed that even
stars seem to be twinkling much more distinctly since the fires
started.

Has anyone noticed a distinct increase in the visual magnitude of
Station with the addition of the P4 solar arrays?
