24 Nov 2019 = 30.3 seconds (from averaged panel temperatures)
25 Nov 2019 = 33.3 seconds (from averaged panel temperatures)
26 Nov 2019 = 40.4 seconds (from averaged panel temperatures)
27 Nov 2019 = 47.0 seconds (from averaged panel temperatures)
28 Nov 2019 = 74.2 seconds (from averaged panel temperatures)

This past week we have noted AO-73 randomly reversing spin direction during passes, some passes exhibiting reverse spin and some normal spin direction.
At times it exhibited a significant tumble that was evident during data downloads.
AO-73’s spin has slowed markedly over this last week which is due potentially to reducing Sun Angle providing decreased Propeller Effect.
