Year: 94  Doy: 153
Observer: koon

COMMENT: Thu Jun  2 17:02:38 GMT 1994
Clear sky, cirrus off to the east (same as last two observing days), wind ~5
mph from the west, temp ~45 F.

Thu Jun 2 17:09:02 GMT 1994: Patrol Start

DPMON COMMENT: Thu Jun  2 17:09:05 GMT 1994
O2B mike is set at 2.000 mm which gave the best solar disk focus last time,
disk exposure set at 7 ms, limb exposure set at 30 ms.


DPMON COMMENT: Thu Jun  2 17:17:16 GMT 1994
Changed disk exposure to 9 ms.


DPMON COMMENT: Thu Jun  2 17:30:33 GMT 1994
Can see a possible loop prominence at PA=277.


DPMON COMMENT: Thu Jun  2 17:44:06 GMT 1994
Changed disk exposure to 100 ms.

DPMON COMMENT: Thu Jun  2 18:36:42 GMT 1994
I have changed the O2B mike setting from 2.000 mm to 4.300 mm, this is the
best setting for focusing the occulting disk ontto the camera.
pl
This is hard to judge by eye but at 4.300 then prominences may look better
although the filaments on the disk have become unfocused.


DPMON COMMENT: Thu Jun  2 18:44:25 GMT 1994
Changed the limb exposure from 300 to 350 ms.


DPMON COMMENT: Thu Jun  2 19:00:09 GMT 1994
Set O2B mike back to 2.000 mm.

DPMON COMMENT: Thu Jun  2 19:39:27 GMT 1994
I will pause the Patrol while I do some manual testing.

Thu Jun 2 19:40:15 GMT 1994: Patrol End

COMMENT: Thu Jun  2 20:03:17 GMT 1994
Extended dome slot.


LOW-L COMMENT: Thu Jun  2 23:50:50 GMT 1994
Changed back to graphics output and modified programs to take fewer flats at
David's request.  Instrument is back up and running.


DPMON COMMENT: Thu Jun  2 23:51:50 GMT 1994
Tried taking images without LSF and with no Heat Rejecting Filter (HRF) or
H-alpha Filter (HAF), the disk image looks very good this way.  But we need
one of those filters to eliminate the IR ring in the limb images, so I tried
the HRF w/ the 0.7" lyot stop (looks good compared to the LSF) and I tried
the HAF w/ the 0.7" lyot stop (looks almost as good) then I saved a disk and
a limb image for each setup for David to look at.  I`ll try to find the best 
focus for each setup and then save the images to tape on Saturday.  Note that
both setups have the filter flat against the stop (not tilted).


MKIII COMMENT: Thu Jun  2 23:59:33 GMT 1994
