29 May 2019 = 162.6 seconds (from averaged panel temperatures)
30 May 2019 = 133.5 seconds (from averaged panel temperatures)
As AO-73 has gradually encountered greater eclipse periods it has developed a cyclic spin period.
Strongly suspect propeller effect and relative point of observation (time and location).
From previous analysis of WOD’s we know spin can vary throughout a 24 hour period.
Will investigate further.
