Cool, clear, no wind.  Cirrus bands to east and to west.

Low-L unit 0 found with tape complete and popped out.  Removed L00027.
Tape L00028 running in unit 1, loaded L00029 into unit 0.


Wed Apr 20 17:15:59 GMT 1994: Patrol Start

MKIII COMMENT: Wed Apr 20 17:17:44 GMT 1994
Since cirrus may obscure sun part of the day, will wait for then or 
noisy sky to do dark scan.

Wed Apr 20 18:01:29 GMT 1994: Filemark-Calibration

COMMENT: Wed Apr 20 18:04:12 GMT 1994
Program may have crashed.  Lost console while listing a file during
rlogin session.  File was some strange binary stuff.


COMMENT: Wed Apr 20 18:22:07 GMT 1994
Rebooted system to recover Console.  Nothing else worked.  Removed P00043,
loaded new tape--P00044.

DPMON COMMENT: Wed Apr 20 19:29:16 GMT 1994
Will run a short series of tests using, first, the 36mm Lyot stop
by itself, then with a dichroic heat rejecting glass in front of it.


MKIII COMMENT: Wed Apr 20 19:31:18 GMT 1994
Changing limb and ref exposures to 27.

Wed Apr 20 19:40:43 GMT 1994: Patrol Start

DPMON COMMENT: Wed Apr 20 19:52:17 GMT 1994
Placed dichroic heat-rejecting glass in front of Lyot stop.


DPMON COMMENT: Wed Apr 20 19:55:36 GMT 1994
Glass was in envelope labelled  R-457   650



DPMON COMMENT: Wed Apr 20 19:58:37 GMT 1994
Ring still visible.  Switching to glass from envelope labelled 
stock # 4063.

Wed Apr 20 20:02:17 GMT 1994: Filemark-Calibration

DPMON COMMENT: Wed Apr 20 20:02:52 GMT 1994
Calibration done with diffuser exposure of 80.  I did not change that one.

DPMON COMMENT: Wed Apr 20 20:12:49 GMT 1994
Changed exposures from 27 (and 80 for diffuser) to 50.
Rings gone, or at least very dim.


DPMON COMMENT: Wed Apr 20 20:16:37 GMT 1994
Looks like there might be a faint ring inside the occulting disk
edge visible.


COMMENT: Wed Apr 20 20:21:38 GMT 1994
Need to open top of dome.  MKIII continues.

DPMON COMMENT: Wed Apr 20 20:31:12 GMT 1994
This glass, stock#4063, looks like it might do the trick,  will
leave it in for a while at exposure setting 50.

Wed Apr 20 21:01:17 GMT 1994: Filemark-Calibration

MKIII COMMENT: Wed Apr 20 21:14:47 GMT 1994
Sky very noisy.  Will do a dark scan.
