Sun May 1 19:01:16 GMT 1994: Filemark-Calibration COMMENT: Sun May 1 19:06:13 GMT 1994 Cold southwest (downslope) wind gradually picking up, ~5 mph now. Two large but relatively quiescent prominences on the west limb, there`s a fair amount of structure visible in the large loop at PA=235, and a series of smaller loops at PA=260-280 may be associated with one or more large Active Regions, no coronal changes noticed yet. DPMON COMMENT: Sun May 1 19:51:51 GMT 1994 Pausing to extend slot. Will also do some manual testing with two other Lyot stop apertures (11 and 20 mm) will save some images to tape for both. Sun May 1 20:13:44 GMT 1994: Patrol Start DPMON COMMENT: Sun May 1 20:13:53 GMT 1994 Installed 20mm Lyot stop with blue filter, set exposure to 115.

Sun May 1 21:00:35 GMT 1994: Filemark-Calibration COMMENT: Sun May 1 21:17:57 GMT 1994 $$$ Orographic clouds getting very thick, lots of clouds upwind, closing down. DPMON COMMENT: Sun May 1 21:18:58 GMT 1994 I'm not sure if any good images were taken through the clouds with the 11.4mm Lyot stop and blue filter, but the prominences did look sharper when I saw some good Monitor images.
