Clear sky, light southwesterly wind, temp=50 F.

4-station wheel was running away, rebooted plessey to fix.
Also, trying a quick test of the smaller aperture lyot stop (1/2 diameter).

The 4-station wheel was stuck with only half the light getting through after
I rebooted the plessey.  The calibration routine (which moves the 4-station
wheel) cleared up the problem.  Will pause again for a quick aperture test.

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.
