Looks like we must have had a lot of rain last night due to ponding and run off on the road. ___end___ Wed Jul 01 16:55:50 GMT 2015 COMP Start Patrol KCOR COMMENT BY berkey: Wed Jul 01 17:03:54 GMT 2015 T- beam focus looks horrible this morning. I think we may be having an issue with the camera focus stage having some problems with the motion at that it extreme front of its range. To fix this I think should move the the stage forward (toward to the beam splitter) so we can back the focus to the middle of its range. ___end___ Wed Jul 01 17:09:24 GMT 2015 KCOR Start Synoptic Patrol Wed Jul 01 17:16:42 GMT 2015 KCOR End Patrol KCOR COMMENT BY berkey: Wed Jul 01 18:35:49 GMT 2015 Taking some flat data to characterize camera linearity response.

The T-cam stage was moved .15" with the gauge blocks forward to bring the focus stage back ~.15" such that it will be more centered in its range of travel. Using the distortion grid we peaked up tip/tilt focus on both cameras. If we weren't making in silly mistakes both cameras should look a lot better when we go back on sky. We did find we were never able to get the south side of the T-cam focus to come into alignment. Perhaps this suggests some of the camera lenses are misaligned; if so we will have to send to aft-optics to Boulder for realignment. :( ___end___ GENERAL COMMENT BY berkey: Wed Jul 01 22:36:17 GMT 2015 Its been blowing since about the time we stopped CoMP this morning. ___end___ KCOR COMMENT BY berkey: Wed Jul 01 22:54:15 GMT 2015 Taking dark data to match the flats taken this morning. 1 msec test data 22:46:00->22:48:04 .1 msec test data 22:48:51->22:50:39 .2 msec test data 22:51:27->22:53:16 .3 msec test data 22:54: ___end___ GENERAL OBSERVATORY COMMENT BY berkey: Wed Jul 1 23:44:24 GMT 2015 It just got really dark in here.
