It looks like reset 95 put AO-91 into SAFE mode a few hours ago. Just now I cleared the MIN and MAX values, turned on the transponder for a brief minute or so, and then commanded back to SAFE mode. If you were on the bird during this pass, it should make sense--to observers, the transponder just came up for a minute or so, and then went back off.
We'll watch and see what the battery looks like for the next day or two. Then we'll probably turn the transponder back on and see how it holds up.
