Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun Oct 1 17:02:36 GMT 1995 Year: 95 Doy: 274 Observer: yasukawa console Oct 1 16:57 WEATHER COMMENT: Sun Oct 1 17:03:11 GMT 1995 Cool, clear, Scattered altocumulus, Cirrus and altocumulus deck to west of island. Light southeast wind. COMMENT: Sun Oct 1 17:04:00 GMT 1995 Station in standard power-down state overnight due to hail and thunderstorm. other comments to follow start-up. Sun Oct 1 17:10:48 GMT 1995: Patrol Start DPMON COMMENT: Sun Oct 1 17:11:56 GMT 1995 Optical problem, opal in, taking it out manually. Sun Oct 1 17:13:49 GMT 1995: Patrol Start MKIII COMMENT: Sun Oct 1 17:14:50 GMT 1995 Idrop test. Micro channels A and B swapped, phasing changed from A=b to A=8 and B=5 to B=8. LOW-L COMMENT: Sun Oct 1 17:16:26 GMT 1995 LowL had a "graphic character crash" yesterday afternoon at 22:45:56. L00319 popped. Coelostat stowed. I am not sure if the crash occurred because Darryl concluded his vigil, i.e. the doctor is no longer here, or if the crash had to do with the power-down. DAK's last log entry was at 21:59:20, and I assume that the powerdown may have occurred around the time of the LOWL crash. LOWL itself was not powered down. Loaded L00321 into unit 1. Rebooted LOWL. COMMENT: Sun Oct 1 17:25:35 GMT 1995 GONG xterm restarted. COMMENT: Sun Oct 1 17:38:50 GMT 1995 Going down to GONG shelter to check for problems. COMMENT: Sun Oct 1 17:47:42 GMT 1995 Back at controlroom. Several GONG parameters in red, but Status monitor indicates everything OK in there. I'll wait until the instrument wakes up to see if the connection between the instrument chassis and data chassis re-establishes itself.
