This happens when it gets moderately cloudy, and it comes and goes with the clouds. The normal light level is at about 21.0 Thu Apr 26 22:36:16 GMT 2001 PICS End Patrol WEATHER COMMENT: Thu Apr 26 22:36:46 GMT 2001 Orographic clouds have moved in. COMMENT: Thu Apr 26 22:37:03 GMT 2001 Pausing instruments due to clouds.

Kim will probably remove it and drill out the holes to give better switching. COMMENT: Fri Apr 27 00:32:51 GMT 2001 Darryl heading down for the day. Fri Apr 27 00:33:26 GMT 2001 MkIV
