I'll take a look upstairs.

Sun Jan 24 18:22:14 GMT 1999 MKIII End Patrol **PICS PROBLEM**: Sun Jan 24 18:47:49 GMT 1999 The motor for the filter wheel was disconnected, I connected it and tested it before closing everything back up. The filter wheel works now. WEATHER COMMENT: Sun Jan 24 19:11:08 GMT 1999 It rained for a while, now there is a light rain/fog but sun is shining through. I may be able to observe later. WEATHER COMMENT: Sun Jan 24 20:12:28 GMT 1999 Thin fog still blowing over, it is sunny and the sky is clear above. WEATHER COMMENT: Sun Jan 24 21:30:11 GMT 1999 Fog/rain cleared, sky is mostly clear except for scattered cirrus and heavy thunderclouds to the SE, very windy at 35+ gusts, very cold outside. trol COMMENT: Sun Jan 24 21:32:26 GMT 1999 Restarted observations. **PICS PROBLEM**: Sun Jan 24 21:39:23 GMT 1999 Still no images, I'll pause and go check out the camera connections.

I tested the shutter in Video mode and could hear and see it open and close, but the Camera window looks the same way it did when I tried Patrol, it is gray with white horizontal noise streaks that move around with each exposure/image. COMMENT: Sun Jan 24 22:14:35 GMT 1999 I'm bumping the spar now and then and affecting the observations of the other instruments as I work on the PICS. Sun Jan 24 22:21:59 GMT 1999 MKIII Start Cal **PSPT PROBLEM**: Sun Jan 24 22:23:40 GMT 1999 The last image is vignetted, similar to the problem I had last week, can only see left sliver of the sun and that is moved into the middle of the image area. Closing down due to nearby clouds. WEATHER COMMENT: Sun Jan 24 22:26:52 GMT 1999 A huge wall of clouds is approaching from the East. **PICS PROBLEM**: Sun Jan 24 22:28:19 GMT 1999 The Camera window didn't change despite taking images with the PICS cover open, and with many different combinations of filter wheel positions and exposure times and objective wheel positions and filter stage positions and occulting wheel positions. Maybe the recent software and/or hardware changes are incompatible with something. I will close it back up, I didn't get a chance to do the Halle Filter Test because of this problem. MKIV COMMENT: Sun Jan 24 22:36:20 GMT 1999 Unfortunately the cirrostratus moved in before the calibration ended. I didn't get a chance to do the Height Mask Tests due to poor weather. WEATHER COMMENT: Sun Jan 24 22:37:41 GMT 1999 The cirrostratus has arrived and the lower clouds aren't far behind, closing down for the day.
