WEATHER COMMENT: Wed Mar 8 20:32:10 GMT 2000 Cirrostratus is thin now but thicker stuff is coming. **CHIP PROBLEM**: Wed Mar 8 20:34:33 GMT 2000 Was stalled with Program:Fixcenter and Optics: Busy, not sure how long since I was working on the PSPT, but it was cloudy anyway. Did a Kill/Run cycle to fix. **PSPT PROBLEM**: Wed Mar 8 21:00:40 GMT 2000 I watched a full calibration sequence and didn't see any mirror oscillation or focus related fuzzy images, yay! For now things are good, but as the solar image size gets smaller we may run into problems with unstable mirror oscillations because the quadcell telephoto lens is adjusted for the largest image size right now and it may need to be increased as the solar image size decreases in the summer. WEATHER COMMENT: Wed Mar 8 21:26:08 GMT 2000 Much thicker clouds, pausing instruments. 1:32:09 GMT 2000 PICS End Patrol Wed Mar 8 21:54:11 GMT 2000 CHIP ending tape COMMENT: Wed Mar 8 22:15:14 GMT 2000 TAPES: ****** MKIV: 00068 CHIP: C01067 PICS: P01686 LOWL: L00675 in drive #0 Wed Mar 8 22:17:45 GMT 2000 MkIV
