Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sat Jun 4 17:14:07 GMT 1994 Year: 94 Doy: 155 Observer: koon COMMENT: Sat Jun 4 17:14:33 GMT 1994 Scattered cirrus clouds, wind ~5 mph from the east, temp ~50 F. Sat Jun 4 17:21:18 GMT 1994: Patrol Start DPMON COMMENT: Sat Jun 4 17:34:09 GMT 1994 Limb exposure is at 350 ms, I just changed the disk exposure to 70 ms. The new H-alpha filter is installed over the 0.7" Lyot stop, O2B focus mike is set to 4.300 mm. Sat Jun 4 18:01:22 GMT 1994: Filemark-Calibration MKIII COMMENT: Sat Jun 4 18:24:06 GMT 1994 Just did a channel 1 cal, will do a channel 0 cal next. DPMON COMMENT: Sat Jun 4 18:24:42 GMT 1994 Program crashed while I was checking the closeup solar features by pointing to area of interest in the full disk image and clicking a mouse button to update the closeup view window, this is usual procedure, first time I`ve seen it crash like this, will restart and install a new tape. DPMON COMMENT: Sat Jun 4 18:48:38 GMT 1994 Had to reboot computer after the crash, starting new tape P00072. LOW-L COMMENT: Sat Jun 4 18:49:32 GMT 1994 Still running, tape L00053 an drive #0. DPMON COMMENT: Sat Jun 4 18:50:18 GMT 1994 Will start off with a few images taken with the setup used earlier, then I will pause the Patrol program and do some manual testing, I will save various test images for review in Boulder and I will save data to tape for the best setup of different filter/stop combinations. Sat Jun 4 18:56:02 GMT 1994: Patrol End DPMON COMMENT: Sat Jun 4 18:56:10 GMT 1994 Both the Daystar filter and the diffuser are moving in and out of the light path. Will pause the Patrol and reset the Plessey and reset the filter and diffuser. Sat Jun 4 18:58:57 GMT 1994: Patrol Start Sat Jun 4 19:00:22 GMT 1994: Filemark-Calibration DPMON COMMENT: Sat Jun 4 19:05:17 GMT 1994 Restarted the Patrol for some base images. DPMON COMMENT: Sat Jun 4 19:11:47 GMT 1994 Pausing the Patrol for some manual testing. Sat Jun 4 19:13:02 GMT 1994: Patrol End Sat Jun 4 19:43:17 GMT 1994: Patrol Start DPMON COMMENT: Sat Jun 4 19:43:23 GMT 1994 Taking some data with the "close-to-best" focus setting for O2B of 2.500 mm. Using new H-alpha filter mounted flat on 0.8" Lyot stop, disk exposure is 70 ms, limb exposure is 350 ms. Not sure if the limb is at best focus but disk is close. DPMON COMMENT: Sat Jun 4 19:51:59 GMT 1994 Diffuser and Daystar filter moving in and out again, will reset as before. COMMENT: Sat Jun 4 19:52:51 GMT 1994 Some cirrus clouds are getting close. Sat Jun 4 19:54:13 GMT 1994: Patrol End DPMON COMMENT: Sat Jun 4 19:56:17 GMT 1994 Lost the Display and Focus windows again, this time while running Manual. The core gets dumped to memory and /opt gets full. As before, I will delete core, reboot and start on a new tape. DPMON COMMENT: Sat Jun 4 20:25:41 GMT 1994 Crashed in Manual mode this time with the Camera field showing "busy", this crash has happenned in the past, had to reboot the computer but kept the same tape since it had no data on it. Doing more manual testing now. COMMENT: Sat Jun 4 20:39:18 GMT 1994 Cirrus clouds passing by. DPMON COMMENT: Sat Jun 4 20:55:56 GMT 1994 Crashed again while in manual mode, Camera "busy. Rebooting. DPMON COMMENT: Sat Jun 4 21:04:43 GMT 1994 Testing is getting really slowed down by crashes and cirrus. DPMON COMMENT: Sat Jun 4 21:48:57 GMT 1994 Crashed again in manual mode, rebooting. DPMON COMMENT: Sat Jun 4 22:02:42 GMT 1994 Crashed again while trying to run Continuous after having run Continuous (Manual mode) and saving an image in the data directory. This seems to be the recurring pattern. Rebooting. DPMON COMMENT: Sat Jun 4 23:05:10 GMT 1994 Crashed again in Manual mode the same way as listed last time. Rebooted. Sat Jun 4 23:12:16 GMT 1994: Patrol Start DPMON COMMENT: Sat Jun 4 23:12:18 GMT 1994 Starting up Patrol on 3rd tape for today (P00073). The heat rejection filter is on the 0.8" Lyot stop (old), the O2B mike is at 4.300 mm, the disk exposure started at 70 ms but I just changed it to 130 ms, the limb exposure started at 350 ms but I just changed it to 300 ms. Limb is washed out due to passing cirrus, but disk features can still be seen. This seems to be the best setup for disk images with a filter for IR rejection. Still need to work on the limb images though. DPMON COMMENT: Sat Jun 4 23:54:53 GMT 1994 Cirrus is temporarily gone, changed the limb exposure to 350 ms. Sun Jun 5 00:01:11 GMT 1994: Filemark-Calibration Sun Jun 5 00:45:02 GMT 1994: Patrol End DPMON COMMENT: Sun Jun 5 00:45:06 GMT 1994 Activity report: QP: 93; 128; 315. No coronal activity. TAPES: MKIII: H00769 DPMON: P00071, P00072, P00073 LOW-L: L00053 in drive #0 until it crashed at 23:56 (see below), removed L00053 from drive #0 and installed L00055, removed L00054 from drive #1 and installed L00056. MKIII COMMENT: Sun Jun 5 00:52:47 GMT 1994 Doing dark scan now. LOW-L COMMENT: Sun Jun 5 00:52:58 GMT 1994 Just noticed that it crashed at 23:56, loaded new tapes and restarted.
