They appear to be blowing in from the southwest and according to the satellite images we may remain on the cusp of the cloud bands for a while, but time will tell. ___end___ Tue Nov 23 19:40:01 GMT 2021 Running UCOMP Cookbook 1079_Pol_Calibrate.cbk line 0 Tue Nov 23 19:44:04 GMT 2021 Running UCOMP Cookbook waves_1074_1hour.cbk line 0 Tue Nov 23 19:47:34 GMT 2021 KCOR End Calibration Script Tue Nov 23 20:56:31 GMT 2021 UCoMP Paused for clouds WEATHER COMMENT: mcotter: Tue Nov 23 20:58:35 GMT 2021 Temp: 52.5f, Humidity: 13%, Pressure: 28.817in, Wind: 6mph from 24degs, Skies: Cirrus has moved into the viewing area from the south. Wisps of Altocumulus clouds are also begin to form over the observatory. ___end___ GENERAL COMMENT BY mcotter: Tue Nov 23 20:58:55 GMT 2021 Both Kcor and Ucomp have been paused for clouds. ___end___ **UCoMP PROBLEM COMMENT BY mcotter** : Tue Nov 23 22:59:41 GMT 2021 Steve had advised us that he saw that there was a problem with one of the heating elements within the instrument. When the instrument was paused for clouds I opened Ucomp up and did an inspection. The the Watlow Controller had no output voltage to the relay and there appeared to be no power going to the unit. Upon closer inspection I found that the power connector was not fully inserted into the Watlow Controller, thus no power to the heating element. After a short period of time the temps came up to normal operating levels. ___end___ GENERAL COMMENT BY mcotter: Tue Nov 23 23:01:04 GMT 2021 Beautiful and clear in the early morning. By late morning Cirrus was moving in and eventually the sky became too bright to observe. ___end___ GENERAL COMMENT BY mcotter: Tue Nov 23 23:04:00 GMT 2021 Continued to repair the control unit and motors for the adjustable control desk height movement. The broken wiring and connectors have been repaired. I still have to sync the motors, but hopefully after that it will be operational and I can install. ___end___ GENERAL COMMENT BY mcotter: Tue Nov 23 23:04:56 GMT 2021 Emptied trash containers in the dome and control room. ___end___ Tue Nov 23 23:21:12 GMT 2021 UCoMP Restarted from pause
