AO7 orbit 55749, possible problem?

According to my notes, the bird switches from MODE A to MODE B (or back to
MODE A) at approx 2100 UTC every day.  Today, it was supposed to be in mode
A.  According to the AO7 log, it made the switch to MODE A, but apparently
switched back to mode B.

When the bird made a pass at my QTH around 0040 UTC, I did not hear a peep
on MODE A or MODE B.  Normally I hear LOTS of signals.

Indication of a problem?
