What could cause this?


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?
