                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd shift: Noel Camron Hastings
     I opened the dome at 18:24 to begin cooling of the telescope. I
packaged up the filters from Rene Walterbos' previous run and replaced
the hydrogen emission lamp with an argon, returning the cal lamps to
original configuration. The seeing was incredibly poor all night, but
the sky was clear. All systems ran well.
     Around 02:30 MDT water started to run out of the ceiling in the
bathroom. I removed the ceiling tile and found the clean room humidifier
leaking water. I removed the wires to the solenoid controlling water
flow and that seemed to effectively close the valve and stop the leak.
Problem report submitted.
