                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 We were able to open on time with mostly clear skies even though
 there was a radar return slowly headed our way from north of
 Tularosa. We closed when cloud cover appeared to be threatening
 and lightning strikes were under 25 km away. About 20 minutes
 after closing we did receive a short rain shower. We reopened
 at 23:00 for the rest of the night. Skies never stayed photometric
 for much more than 15 or 20 minutes at a time.
 No problems.
