Hello from a fellow Northern Californian!

I was watching the same object at about the same time.  In PPAS
database format, I recorded this observation

95- 58 B 96-09-02 03:38      JEV  54.4 0.3  25  2.18 AA

i.e., 25 flashes in 54.4 sec for a period of 2.18 seconds.

Satellites database, see

This a beautiful satellite -- if I had to make up a top ten list,
this one would be on it.
