Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun Aug 14 16:28:45 GMT 1994 Year: 94 Doy: 226 Observer: chu WEATHER COMMENT: Sun Aug 14 16:28:54 GMT 1994 Clear, cold, light wind from South. Temp 51F. Humidity 87%. Sun Aug 14 16:31:01 GMT 1994: Patrol Start MKIII COMMENT: Sun Aug 14 16:34:40 GMT 1994 Beginning observing day while MKIII and skytx still domed out. LOW-L COMMENT: Sun Aug 14 16:36:29 GMT 1994 Celostat not pointing indicating that the Low-l has crashed. Will attempt a reboot. LOW-L COMMENT: Sun Aug 14 16:56:50 GMT 1994 Removed L00092 from unit 0. Moved L00093 from unit 1 to unit 0. Inserted L00094 into unit 1. Low-l sucessfully rebooted, now running smoothly. MKIII COMMENT: Sun Aug 14 17:00:54 GMT 1994 MKIII and skytx now clear of dome. Sun Aug 14 17:02:15 GMT 1994: Calibration MKIII COMMENT: Sun Aug 14 17:10:29 GMT 1994 MKIII died after first few scans of the day. Tried "Programmer does forget task" and "octal" commands on Tek 4006 and La-120. Finally had to reboot 11/44. Don't think there were any good scans on the exabyte before this time, so I just recycled the tape. Running smoothly now. Sun Aug 14 18:02:14 GMT 1994: Calibration MKIII COMMENT: Sun Aug 14 18:13:58 GMT 1994 MKIII died again. Consulted EAY. Forced to reboot 11/44 again. This time will save current tape, H00821, since it has approx. 1/2 hour worth of data at beginning of the day. Tape does not have double EOF. We think that the problem is the La-120 is locking up during coronal "1take". Hopefully rebooting 11/44 and waiting a while before restarting will solve the problem. MKIII seems to be running normally now. Sun Aug 14 19:02:14 GMT 1994: Calibration DPMON COMMENT: Sun Aug 14 19:35:24 GMT 1994 Configured the Dpmon to disk preferred mode. DPMON COMMENT: Sun Aug 14 19:57:39 GMT 1994 Reconfigured the Dpmon to limb preferred mode. COMMENT: Sun Aug 14 19:58:48 GMT 1994 Reconfigured the dome slot.
