[amsat-bb] AO-92 fading

[Paul Stoetzer]

All of the Fox-1 satellites seem to spin faster or slower depending on
orbit illumination or other factors.

For example, this is the +Z panel rotation on AO-92 since launch.

Someone more well-versed in these matters can comment further on what
causes this, but it is definitely not an indication of the health
status of the satellite.
