Searching for satellite signal 771

Just received a message on my HR21-100 about not having satellite signal and on the "More Info" note it said I should reset my receiver.

I reset it and I am back. But strange that it lost signal. Is it common? It is foggy here in Santa Clara, CA but it is like this almost every morning.

I am running 0x255, fyi.
