AO-73 – Funcube 1

Spin Period

10 May 2019 = 39.5 seconds (from averaged panel temperatures)
11 May 2019 = 60.6 seconds (from averaged panel temperatures)
12 May 2019 = 96.4 seconds (from averaged panel temperatures)
13 May 2019 = 166.5 seconds (from averaged panel temperatures)
14 May 2019 = 176.7 seconds (from averaged panel temperatures)
15 May 2019 = 178.0 seconds (from averaged panel temperatures)
16 May 2019 = 188.8 seconds (from averaged panel temperatures)

As of today (16th May) we now experiencing 15.5 minute eclipse periods per orbit.
Come early June we will stabilise at 20 minutes per orbit until early July when the
eclipse periods again shorten such that we again enter full sun on the 9th August.

In recent days AO-73 has achieved stable spin about the Z-Z axis with minimal Nutation.
