                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 It was clear at sunset, but with rising humidity and promise of
 storms on the way.  We obtained sky flats and focused in haste
 (enough that I forgot to log the focus), then got less than an
 hour's data in poor seeing conditions before the humidity got high
 enough to force a closure.  We got some heavy rain and lightning,
 followed by persistent clouds.
