Rotation Period

26 Jun 2020 = 31.4 seconds (from averaged panel temperatures)
27 Jun 2020 = 29.9 seconds (from averaged panel temperatures)
28 Jun 2020 = 29.1 seconds (from averaged panel temperatures)
29 Jun 2020 = 28.5 seconds (from averaged panel temperatures)
30 Jun 2020 = 27.5 seconds (from averaged panel temperatures)
01 Jul 2020 = 26.4 seconds (from averaged panel temperatures)
02 Jul 2020 = 25.7 seconds (from averaged panel temperatures)

AO-73 continues to rotate in the reverse of its normal spin direction with a high level of Nutation.

AO-73 was noted on the 14th June to have reversed its spin direction.
On all the early morning passes over VK AO-73 exhibit reverse spin.
On a random audit of the evening passes over VK, AO-73 has been observed doing what is known as The Dzhanibekov Effect ( changing rotation direction during the pass).
It is interesting to note that the evening passes over VK have just come out of eclipse prior to AOS, whereas the morning passes are now entering eclipse mid pass.
