Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sat Jun 3 18:17:27 GMT 1995 Year: 95 Doy: 154 Observer: koon console Jun 3 18:14 WEATHER COMMENT: Sat Jun 3 18:17:35 GMT 1995 Clear sky, wind=10 mph from the East, temp=40 F. Sat Jun 3 18:21:53 GMT 1995: Patrol Start LOW-L COMMENT: Sat Jun 3 18:55:36 GMT 1995 Program crashed yesterday at 6/3 0311 ut. It was writing to drive #1 for some reason although earlier the same day (local day) it was writing to drive #0, it normally doesn't switch to a different drive in the middle of the local day, it had written 100 scans to drive #1. I have reset the computer and also plugged in the 486 PC to the same power strip to see if it crashes when the Low-l PC crashes next time. Sat Jun 3 19:00:58 GMT 1995: Calibration LOW-L COMMENT: Sat Jun 3 19:01:49 GMT 1995 Removed L00250 from drive #0, switched L00251 from drive #1 to drive #0, installed L00252 in drive #1. LOW-L COMMENT: Sat Jun 3 19:05:44 GMT 1995 Forgot to mention that the instrument head was pointing down in the stowed position after yesterday's crash. DPMON COMMENT: Sat Jun 3 19:11:49 GMT 1995 Diffuser was running away, fixed it. nd Sat Jun 3 19:12:34 GMT 1995: Patrol Start Sat Jun 3 20:01:04 GMT 1995: Calibration COMMENT: Sat Jun 3 20:08:14 GMT 1995 Extended dome slot.

Sat Jun 3 23:02:01 GMT 1995: Calibration COMMENT: Sat Jun 3 23:03:05 GMT 1995 I couldn't find a dome position that let light through to MKIII, dPMon, and guider at the same time. There is however a particular dome to spar orientation in which the dome slot transmission box makes contact with the snout of the MKIII, this happens when the spar is pointing straight up and the dome is rotated to have the opening facing West. It is better to point the dome to the East if needed to illuminate the guider and block the dPMon, or we might be able to keep rotating the dome to the West a little at a time keeping the MKIII and the guider illuminated while ignoring the blockage of light to the dPMon. The dPMon might be blocked for about 30 minutes or so around 12:45 HST but it is unavoidable sometimes. I had to remove the MKIII O1 to blow off the paint chips that got onto it when the dome to snout contact occurred. Everything is back to normal now. DPMON COMMENT: Sat Jun 3 23:12:44 GMT 1995 There is a big prominence at PA=100-110, but it is not doing anything noticeable.
