With the current wind direction there is very little turbulance on the spar/pspt tube ___end___ Fri Dec 26 17:58:43 GMT 2014 COMP Start Patrol Fri Dec 26 18:05:41 GMT 2014 KCOR Start Synoptic Patrol CoMP COMMENT BY berkey: Fri Dec 26 18:05:04 GMT 2014 I had a lot of trouble getting the comp E/W occulting stage aligned this morning. For some reason the CoMP.vi didnt read the current position when it started up and assumed 0. Moving from this position I compltely lost the pointing. KMy initial attempt to recover involved manually driving the occulter in by turning the NSC200 knob while looking at the solar image with the comp cover off. This. This realigned the occulter but I still had trouble controlling it from CoMP.vi Next I re-homed the E/W motor (manually with the knob), then put the opal in the beam and used the center occulter.vi to drive the occulter back to the center. I am not sure I understand why the vi lost control of the motor in the first place, and I wish we had some way to investage this deeper. But I think that from now on, putting the occulter in the beam to fix a grossly misaligned comp occulter is probally the fastest safest way to proceed. ___end___ GENERAL OBSERVATORY COMMENT BY berkey: Fri Dec 26 18:25:14 GMT 2014 Some flaring seen in AR2249 around 18UT in the gong halpha data. ___end___ Fri Dec 26 19:39:18 GMT 2014 KCOR End Patrol Fri Dec 26 19:39:19 GMT 2014 KCOR Start Calibration script: c:\kcor\mlso-calibration22deg.ini Fri Dec 26 19:55:11 GMT 2014 KCOR End Calibration Script Fri Dec 26 19:55:27 GMT 2014 KCOR Start Synoptic Patrol Fri Dec 26 19:55:27 GMT 2014 KCOR Start Synoptic Patrol Fri Dec 26 20:56:30 GMT 2014 KCOR End Patrol Fri Dec 26 20:56:31 GMT 2014 COMP End Patrol Fri Dec 26 21:03:27 GMT 2014 COMP Start Patrol GENERAL OBSERVATORY COMMENT BY berkey: Fri Dec 26 21:06:40 GMT 2014 Winds seem to be clocking around to the west. Sgs realigned to kcor/comp Lower shutter moved down to act as a bit of a wind sheild as we start pointing twoard the west. ___end___ Fri Dec 26 21:12:23 GMT 2014 KCOR Start Synoptic Patrol KCOR COMMENT BY berkey: Fri Dec 26 23:39:13 GMT 2014 Kcor realtime image brightness seems to be chaning from fram to frame. I am notsly noticing out of the corner of my eye. The guiding, seeing and skies seem ok so I am not sure what is causing this. I am not seeing a trend toward higher or lower values just a bit of "flashing" in brighter/darker images. ___end___ GENERAL OBSERVATORY COMMENT BY berkey: Fri Dec 26 23:54:44 GMT 2014 We are starting to hit our wind limit. ___end___ Sat Dec 27 00:01:01 GMT 2014 COMP End Patrol Sat Dec 27 00:01:01 GMT 2014 COMP Start Patrol Sat Dec 27 00:02:13 GMT 2014 KCOR End Patrol Sat Dec 27 00:02:13 GMT 2014 COMP End Patrol Sat Dec 27 00:07:34 GMT 2014 COMP Start Patrol Sat Dec 27 00:07:42 GMT 2014 KCOR Start Synoptic Patrol GENERAL OBSERVATORY COMMENT BY berkey: Sat Dec 27 01:34:06 GMT 2014 move the lower shutter back up. ___end___ Sat Dec 27 02:00:10 GMT 2014 KCOR End Patrol Sat Dec 27 02:00:31 GMT 2014 COMP End Patrol Sat Dec 27 02:00:45 GMT 2014: PSPT Abort Patrol Sat Dec 27 02:00:50 GMT 2014: PSPT Abort Patrol GENERAL OBSERVATORY COMMENT BY berkey: Sat Dec 27 02:13:34 GMT 2014 still windy but most of the data sermed ok.
