Larry, we appreciate you asking. It's good that the power seems good at night, but the capacity of the battery is still very limited. In fact, 91 has its computer turned off so it sends no telemetry and does not send every 2 minutes if not being used, all to save the battery. If you heard it at night, someone must be using it without paying attention to our request.
The reason for all this is that If the battery gets drawn down too far too many times, it will fail totally--often shorted--and that would mean no transponder in the daytime either.

I am curious if we are still not supposed to be using the transponder during eclipse? I've been away from sats for a bit, and the downlink sounds strong here in FN41 during the late night passes.
Hello Larry,
On this page:
https://www.amsat.org/two-way-satellites/
you'll find notes for each satellite. AO-91 (and -92) has a note beside it that says "Do not attempt to access in eclipse".
