Sun Feb 26 18:03:02 GMT 1995: Calibration Sun Feb 26 19:00:02 GMT 1995: Calibration MKIII COMMENT: Sun Feb 26 19:11:08 GMT 1995 No coronal activity. Will begin setup for channel 1 alignment shortly, then stop MKIII obs to work on alignment. Sun Feb 26 20:00:02 GMT 1995: Calibration MKIII COMMENT: Sun Feb 26 20:53:43 GMT 1995 Went thru the focus iterations again and again confirmed that on chan 1, anyway, I did not see any significant changes in peak separation. The P and the S separation are very close, 5.6 and 5.4 divisions respectively. I did manage to sharpen upo the outer peak of the S detector by adjusting the overall focus 1 turn CCW (detector moves forward), from a 3 pixel "flat" to a 1 pixel point. Without first doing a correction, I will document the height changes, if any, for chan 1 first.

MKIII COMMENT: Sun Feb 26 21:24:14 GMT 1995 CORRECT pau. Resuming mkiii observations. Documenting corrector table. WEATHER COMMENT: Sun Feb 26 21:52:06 GMT 1995 Wind upslope, sky very noisy. Sun Feb 26 22:02:56 GMT 1995: Calibration COMMENT: Sun Feb 26 22:41:59 GMT 1995 It is getting to that time of year where we will need to begin opening the top of the dome shutter around midday. Sky transmission is not shaded, but is probably being vignetted by the dome. Sky tx is now 580. Spar guider is partially shaded at the very north edge.
