                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Before sunset, we were just a few miles on the good side of a very
 nasty weather front.  Just around sunset, the wall of clouds reversed
 direction and crashed upon APO.  And then swirled around for the
 remainder of the night.  Blame Atsuko, who late in the afternoon said
 loudly to the sky "Heaven forbid!" that they should have to run the
 Apache Wheel tonight.  And Heaven complied.
