Hi Allen,

Good thought, but it is definitely too early.  If you follow the AO-27 
orbit using something 3D,  and center over the south pole,  you will see 
that AO-27 never goes into eclipse this time of year.  My simulation shows 
it doesn't go into eclipse until 9 May at 07:37 UTC and even then only for 
less than a minute.

My guess is that it hit a low power condition and turned off.  With luck 
the batteries are still in good condition and the satellite can be turned 
back on again.

73,

Emily
