Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Mon Mar 28 17:47:28 GMT 1994 Year: 94 Doy: 087 Observer: koon COMMENT: Mon Mar 28 17:47:42 GMT 1994 Clear sky, light southwesterly wind, temp=50 F.

Also, trying a quick test of the smaller aperture lyot stop (1/2 diameter).

The calibration routine (which moves the 4-station wheel) cleared up the problem. Will pause again for a quick aperture test. Mon Mar 28 20:05:02 GMT 1994: Patrol End MKIII COMMENT: Mon Mar 28 20:05:28 GMT 1994 Noticed 2 dark steaks radially outward from the limb in the west on the last difference image. DPMON COMMENT: Mon Mar 28 20:21:23 GMT 1994 NOTE: The half-diameter luot stopp is in place (~0.7"), I will increase the exposure from 27/100 to 80/100 and run the Patrol program for 15 minutes. With this stop in place there is no refraction ring around the sun anymore. Excuse my typing, luot stopp = lyot stop. Mon Mar 28 20:26:32 GMT 1994: Patrol Start DPMON COMMENT: Mon Mar 28 20:38:42 GMT 1994 Trying images with exposure set back to 27 for a while. DPMON COMMENT: Mon Mar 28 20:42:42 GMT 1994 Set exposure back to 80. DPMON COMMENT: Mon Mar 28 20:52:07 GMT 1994 Stopping Patrol to remove small lyot stop and extend dome slot.
