The skies are a little bright but the synoptic images look good. Polarization checked good: Mid, Bright, Dark, Mid. The threshold level was changed from 15000 to 10000. ___end___ Tue Feb 15 17:58:18 GMT 2022 Running UCOMP Cookbook 1079_Scan.cbk line 0 Tue Feb 15 18:00:07 GMT 2022 Running UCOMP Cookbook all_wavelenght_coronal_flat.cbk line 0 Tue Feb 15 18:47:50 GMT 2022 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 0 ****Possible CME in Progress mcotter**** : Tue Feb 15 18:48:22 GMT 2022 Observers report with high confidence a CME seeing launching near PA 300 deg, with a minimum width of 10 deg, at UT time 18:06:12. This event is just beginning. Additional alerts may be sent out as more information becomes available. ___end___ Tue Feb 15 21:26:14 GMT 2022 UCoMP Paused for clouds Tue Feb 15 21:27:33 GMT 2022 UCoMP Restarted from pause Tue Feb 15 21:32:42 GMT 2022 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 34 Tue Feb 15 21:34:05 GMT 2022 UCoMP Paused for clouds WEATHER COMMENT: mcotter: Tue Feb 15 22:39:22 GMT 2022 Clouds began to come in from the northeast at approximately 11:20am, with additional clouds forming and dissipating above the observatory and in the general vicinity of the viewing area. I tried pausing and then restarting the instruments during periods of blue sky but the clouds became too numerous and I had to stop observing until conditions improved. ___end___ KCOR COMMENT BY mcotter: Tue Feb 15 22:39:55 GMT 2022 Kcor was stopped due to sky conditions. ___end___ UCoMP COMMENT BY mcotter: Tue Feb 15 22:40:19 GMT 2022 Ucomp has been paused due to sky conditions. ___end___ KCOR COMMENT BY mcotter: Tue Feb 15 22:52:59 GMT 2022 This morning when I spoke to Ben regarding the rotation of the Kcor 01 lens that we did yesterday he thought that the rotation was in the wrong direction; we had rotated the lens approximately -45 deg (counter clockwise). Ben told me that the lens should be rotated to it's original position, then an additional +45 deg. (clockwise). At the very beginning of the day a CME was observed launching so I waited before removing the Kcor 01 lens and rotating it as described. Sky conditions became poor at approximately 11:30am HST, so both instrument were stopped. During this period I removed the Kcor 01 lens, rotated it + 90 deg then reinstalled. Sky conditions are still poor, so we are unable to observe with the Kcor instrument at this time and confirm that the adjustment had the desired effect that Ben is looking to accomplish. ___end___ WEATHER COMMENT: mcotter: Wed Feb 16 00:10:35 GMT 2022 Temp: 38.5f, Humidity: 82%, Pressure: 28.782in, Wind: 7mph from 304degs, Skies: The sky has grown more overcast with gray clouds and a light mist periodically blowing through. ___end___ Wed Feb 16 02:12:52 GMT 2022 UCoMP Restarted from pause WEATHER COMMENT: mcotter: Wed Feb 16 02:14:58 GMT 2022 The sky is now totally overcast with a light rain mixed with sleet falling. ___end___ GENERAL COMMENT BY mcotter: Wed Feb 16 02:15:42 GMT 2022 The day started out good then clouds came into the viewing area in the late morning. ___end___ ONSITE STAFF:
