               ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Coughlin
 We started off with a totally opaque sky, but it began to clear 2 hours
 after sunset, and so I opened at 19:30. The sky continued to clear and
 was photometric by 20:30. APOLLO got good returns and did not have any
 problems tonight. Skies stayed photometric until around 0500 when some
 thin high clouds rolled in and stayed until morning, but did not
 prevent useful data from being obtained.
