Quite true, and a little analysis of the pass times over the last 6 months will
reveal the orbit changes.  When I first started working SO-35, back in late
September, the passes were between 0200z and 0330z (1200 and 1330 local), near
worst power conditions.  Now the passes are between 2230z and 0000z (0830 -
1000 local), some 3 1/2 hours earlier and a more illuminated orbit ("best"
orbit for illumination is one which results in passes around sunrise and sunset
- about 2 1/2 hours earlier than the current orbit).  I hope we aren't still
having morning weekend passes when the orbit is in this configuration! :)
