WEATHER COMMENT: Sat Sep 24 16:41:37 GMT 1994
Clear sky, wind ~5 mph from the west, temp ~45 F.

WEATHER COMMENT: Sat Sep 24 18:48:59 GMT 1994
Cirrus moving slowly over from the east.


DPMON COMMENT: Sat Sep 24 18:52:59 GMT 1994
Switched to optimum disk image setup: 3.85 mm, 0.8" LS, 50 mms exp.

Sat Sep 24 19:02:04 GMT 1994: Calibration

DPMON COMMENT: Sat Sep 24 20:00:57 GMT 1994
Switched back to optimum limb image setup.


WEATHER COMMENT: Sat Sep 24 20:01:18 GMT 1994
Occasional cirrus passing by.


DPMON COMMENT: Sat Sep 24 20:01:43 GMT 1994
Nothing good on disk and limb to focus O2A by.


MKIII COMMENT: Sat Sep 24 20:02:20 GMT 1994
Will look into tilt plate operation to see if it is working OK, may be able
to improve design if necessary.


COMMENT: Sat Sep 24 20:59:43 GMT 1994
Extended dome slot and turned on the ADR.


WEATHER COMMENT: Sat Sep 24 21:00:10 GMT 1994
Getting cirrus from the west passing overhead.

Sat Sep 24 21:02:04 GMT 1994: Calibration

DPMON COMMENT: Sat Sep 24 21:54:02 GMT 1994
Diffuser runaway. Recycled plessy to correct.

Sat Sep 24 21:58:03 GMT 1994: Patrol End

COMMENT: Sat Sep 24 22:07:45 GMT 1994
Stopping obs to run MKIII tilt plate tests.


MKIII COMMENT: Sat Sep 24 22:51:02 GMT 1994
Checked the operation of the tilt plates with Duc's help.  They seem to work
fine and I can't see any way that they could block the light beam, when they
are out they are clear of the beam by about 1".  Will check the 15 degree
orientation logic more thoroughly, I can't find an easy way into the telescope
near the plates.  Apparently when you orient the plates at 15 degrees they
move all the way in perpendicular to the beam then they each back out about
20 degrees then they move back in and stop at 7.5 degrees from perpendicular
(hopefully).  Found dust floating around inside the telescope, this is 
probably a big contributor to the "noisy sky problem", we will need to flush 
out the air, maybe by putting an air filter in the telescope and blowing the
circulated air out the front hatches near the O1.  The fan for the air
circulation system wasn't working, I tightened the connection and it started
up OK, took apart the connector for inspection but the wires were OK, the
sleeves that fit over the pins on the other half of the connector are probably
enlarged a bit.

Sat Sep 24 23:05:09 GMT 1994: Patrol Start

WEATHER COMMENT: Sat Sep 24 23:07:10 GMT 1994
Thick patches of cirrus moving into FOV.  Orographic clouds also 
closing from South and West.

DPMON COMMENT: Sat Sep 24 23:14:33 GMT 1994
Dpmon appears to be domed out.  Rotated dome and engaging ADR.

Sat Sep 24 23:21:58 GMT 1994: Patrol Start

DPMON COMMENT: Sat Sep 24 23:22:19 GMT 1994
Diffuser apparently didn't reset earlier when we recycled the Plessey
power.  Stopped patrol to manually reset.  Dpmon now operating normally.


WEATHER COMMENT: Sat Sep 24 23:38:33 GMT 1994
Orographic clouds moving through FOV.

Sun Sep 25 00:00:59 GMT 1994: Calibration

COMMENT: Sun Sep 25 00:31:14 GMT 1994
Small orographic clouds have been moving in and out of FOV.  Still
patches of blue sky present.  Will continue to run in hopes of getting
good data in between clouds.

COMMENT: Sun Sep 25 01:57:33 GMT 1994
Reconfigured the dome slot.

Sun Sep 25 02:00:59 GMT 1994: Calibration

WEATHER COMMENT: Sun Sep 25 02:34:31 GMT 1994
In a hole between receding orographic clouds, altocumulus which has
passed to the East,  and cirrostatus moving in from West.
