Thanks Drew!

Hi Don,
All correct, except auto safe mode ends as soon as eclipse does, when the bus voltage goes over 3.6. The batteries will charge then for the next 60 minutes or so until the next eclipse.
As we move to winter in the northern hemisphere, the end of the eclipse should shift over the pole and to the beginning of the descending part of the orbit, and this issue should change for at least the northern hemisphere ops.

From my very limited knowledge, the batteries are dropping to a voltage during eclipse that safe mode is triggered to prevent the batteries from discharging too far and thus preventing damage. Once the satellite is back into illumination it should return to normal operations once the batteries have charged.
AGAIN, this is MY understanding of the situation, and in no way reflects an officatial AMSAT response nor might be accurate.

Today (8/24) at ~4:16 UTC I was attempting to uplink to AO-92 when Veronica announced “FOX-1 Delta, Safe Mode”. Does anyone know what put AO-92 in safe mode, and will this happen every night?
