Fri May 16 22:07:44 GMT 2003 CHIP End Patrol WEATHER COMMENT: Fri May 16 22:07:36 GMT 2003 In thick orographic clouds. Pausing observations and closing domes as a precaution against precipitation. Fri May 16 22:08:29 GMT 2003 PICS End Patrol WEATHER COMMENT: Fri May 16 22:35:11 GMT 2003 In thick fog. **PSPT PROBLEM**: Sat May 17 00:21:07 GMT 2003 PSPT dome shutter motor burned out after stalling during closing. Discovered motor buzzing and smelling of burnt windings. Turned it off--shutter was nearly closed, I hand-cranked it down the last inch or so. Shut-off switch looked like it wasn't quite enabled at that point when range of motion was later tested by manually moving the shutter. Looked for replacement motor but none with the correct specs were available in our spares inventory. Located a local Dayton Motor rep and ordered a replacement that will be on-island on Tuesday. **PSPT PROBLEM**: Sat May 17 00:56:48 GMT 2003 Checked dome shutter limit switch and it is functioning OK. I did not actuate it against the limit actuation cams but the actuators do contact the cams before reaching shutter travel limits and I can hear the switch "click" before the physical limit is reached. WEATHER COMMENT: Sat May 17 01:15:39 GMT 2003 Still in dense fog and light rain.
