Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sat Apr 23 17:21:12 GMT 1994 Year: 94 Doy: 113 Observer: koon COMMENT: Sat Apr 23 17:21:22 GMT 1994 Clear sky, wind ~5 mph from the northwest, temp. = 50 F. Sat Apr 23 17:25:34 GMT 1994: Patrol Start COMMENT: Sat Apr 23 17:29:09 GMT 1994 LOWL: It filled the tape in drive #1 and ejected it and went on to write to drive #0 as it is supposed to do. No crash, no problem. Removed tape L00028 from drive #1 and installed tape L00030 there. COMMENT: Sat Apr 23 17:34:47 GMT 1994 Testing Automatic Dome Rotator today. Sat Apr 23 18:02:13 GMT 1994: Filemark-Calibration MKIII COMMENT: Sat Apr 23 18:42:23 GMT 1994 Depletion noticed on the west limb (PA ~285) from last difference image. Sat Apr 23 19:02:17 GMT 1994: Filemark-Calibration MKIII COMMENT: Sat Apr 23 19:59:24 GMT 1994 Waved a long screwdriver in front of objective to see how this affects the next difference image. Did in one scan in the southeast, then another scan with the waving affecting the data signal in the southwest region, forgot to capture the first scan so I did the second. COMMENT: Sat Apr 23 20:13:25 GMT 1994 The ADR turned on OK but moved the dome too far and the guider telescope got blocked resulting in loss of spar guiding, readjusted the dome, will watch further ADR adjustments. Extended Dome slot. MKIII COMMENT: Sat Apr 23 20:46:49 GMT 1994 Totally blocked the objective from barrel angle 180 to about 270 to try to figure correlation between barrel angle and established position angle coordinate system. Note that when I mentioned waving a screwdriver earlier I should have stated barrel angles 180 to 270 (instead of southwest) and 180 to 90 (instead of sotheast).
