----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Tue Dec 7 18:32:46 GMT 1999 Year: 99 Doy: 341 Observer: yasukawa WEATHER COMMENT: Tue Dec 7 18:33:15 GMT 1999 Cool, clear, brisk southeast wind. COMMENT: Tue Dec 7 18:33:34 GMT 1999 Late start, had to drop kids off at school before leaving town today. Tue Dec 7 18:34:04 GMT 1999 CHIP Startup--Initializing new tape Tue Dec 7 18:37:58 GMT 1999 MKIV Start Patrol Tue Dec 7 18:38:19 GMT 1999 PICS Start Patrol Tue Dec 7 18:38:19 GMT 1999 PICS Start Patrol **LOW-L PROBLEM**: Tue Dec 7 18:51:09 GMT 1999 LOWL found running this morning, but both tapes were popped out. GUI indicating it was set to drive #1, with 4 files in the spool. Removed L00648 from drive #1 amd L00649 froim drive #0, cleaned both drives. LOaded L00650 into drive #0, L00651 into drive #1. Rebooted CPU, set time and date, Restarted LOWL program, writing to drive #0. **CHIP PROBLEM**: Tue Dec 7 18:55:20 GMT 1999 Just did 4th Cancel Wait to get off of Velocity (4th occurrence). **MKIV PROBLEM**: Tue Dec 7 18:55:55 GMT 1999 Haven't been catching all of the phase reversals so far this morning due to LOWL problem. Tue Dec 7 19:03:09 GMT 1999 CHIP Bias Tue Dec 7 19:04:26 GMT 1999 CHIP End Bias Tue Dec 7 19:04:39 GMT 1999 CHIP Water Tue Dec 7 19:05:27 GMT 1999 CHIP End Water **PSPT PROBLEM**: Tue Dec 7 19:42:58 GMT 1999 Still having difficulty with mirror servo Y-axis. Mirror on LED is not turning on and Y meter indicating no attempt to acquire. Troubleshooting it, but without spare parts or boards, and adequate documentation and training, this will be difficult. **MKIV PROBLEM**: Tue Dec 7 19:46:20 GMT 1999 Phasing reversals are frequent and troubleshooting PSPT makes cataching and fixing them hit-or-miss at best. Tue Dec 7 20:03:05 GMT 1999 CHIP Gain Tue Dec 7 20:23:16 GMT 1999 CHIP End Gain Tue Dec 7 20:23:33 GMT 1999 CHIP Bias **CHIP PROBLEM**: Tue Dec 7 20:23:49 GMT 1999 CHIP stuck at -1000, -500 in Gain cal. Cancelled Wait twice to resume. Was troubleshooting PSPT so it was probably stuck a while. Tue Dec 7 20:24:41 GMT 1999 CHIP End Bias Tue Dec 7 20:24:58 GMT 1999 CHIP Water Tue Dec 7 20:25:38 GMT 1999 CHIP End Water Tue Dec 7 21:02:00 GMT 1999 CHIP Bias Tue Dec 7 21:03:03 GMT 1999 CHIP End Bias Tue Dec 7 21:03:18 GMT 1999 CHIP Water Tue Dec 7 21:04:05 GMT 1999 CHIP End Water **PSPT PROBLEM**: Tue Dec 7 21:31:27 GMT 1999 While troubleshooting mirror servo card, pspt suddenly came to life and began running. Checking parameters when it is working. Tue Dec 7 22:02:00 GMT 1999 CHIP Bias Tue Dec 7 22:02:59 GMT 1999 CHIP End Bias Tue Dec 7 22:03:15 GMT 1999 CHIP Water Tue Dec 7 22:04:04 GMT 1999 CHIP End Water Tue Dec 7 22:10:55 GMT 1999 PICS End Patrol **PSPT PROBLEM**: Tue Dec 7 22:13:06 GMT 1999 Mirror servo board seemed to be OK except for mirror on LED being off when mirror wouldn't lock on to sun. Parameters while it was working were similar to when it was not for the meter being pegged at the same side during flat-field offsets. The only other similarity that could be a clue was the pspt suddenly locked on and began running at around the same time it did yesterday at 21-something UT. Both times I was troubleshooting with the instrument running but stalled at the place where it was trying to lock on to the sun. I will need to troubleshoot more to find the problem, in the meantime the exercise is useful in helping me understand what is going on on that circuit board.
