This event was already in progress at the start of observing and was identified using a combination of Kcor NRGF and Kcor Diff Images. ___end___ Sat Jun 04 17:53:21 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 0 Sat Jun 04 18:20:57 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal_flat.cbk line 0 Sat Jun 04 18:36:07 GMT 2022 Running UCOMP Cookbook waves_1074_1hour.cbk line 0 Sat Jun 04 19:45:54 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 0 Sat Jun 04 20:07:11 GMT 2022 KCOR Start Calibration script: c:\kcor\mlso-calibration22deg-20171025.ini WEATHER COMMENT: mcotter: Sat Jun 04 20:09:42 GMT 2022 The sky has some high altitude Cirrus in the south-southwest sky that appears to be moving toward the observatory. So far the sky remains clear and conditions are good, but I will continue to monitor the clouds and watch for any "Brightening" of sky conditions. ___end___ Sat Jun 04 20:14:21 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal_flat.cbk line 0 Sat Jun 04 20:22:25 GMT 2022 KCOR End Calibration Script Sat Jun 04 20:29:32 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 0 Sat Jun 04 20:57:37 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 0 GENERAL COMMENT BY mcotter: Sat Jun 04 21:22:12 GMT 2022 Aerosols are beginning to pick up and the sky is starting to get a little bright. As I look at the Kcor Synoptic images the center of the image adjacent to the coronal ring is beginning to brighten and the image appears to brighten from the center outward. As I mentioned in the log earlier this week, when the sky brightens while observing with Kcor it presents itself in two distinct manners: 1) Brightening from the center outwards, appearing that the coronal ring is brightening and getting larger. 2) The background begins to brighten turning from a dark background, through many shades of gray eventually becoming very light gray or a dark white, all the while maintaining a relatively distinct intact coronal ring until the background washes out the coronal ring. ___end___ Sat Jun 04 21:25:03 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 0 Sat Jun 04 21:44:34 GMT 2022 UCoMP Paused for clouds WEATHER COMMENT: mcotter: Sat Jun 04 21:47:28 GMT 2022 Orographic clouds have moved into the viewing area with the addition of increasing high altitude Cirrus and Cirrostratus clouds. ___end___ KCOR COMMENT BY mcotter: Sat Jun 04 21:48:18 GMT 2022 Kcor has been stopped due to cloud coverage in the viewing area. ___end___ UCoMP COMMENT BY mcotter: Sat Jun 04 21:48:52 GMT 2022 Ucomp has been paused due to clouds in the viewing area. ___end___ ****EVENT COMMENT BY mcotter**** : Sat Jun 04 22:00:19 GMT 2022 A very well defined protrusion has been observed emanating from the southwest quadrant of the Sun (approximate PA 135 deg), beginning at approximately 17:50:01 UT. Unfortunately due to clouds in the viewing area observations were paused at approximately 21:48:00. As soon as the viewing area clears observations will continue. ___end___ WEATHER COMMENT: mcotter: Sat Jun 04 23:14:24 GMT 2022 The sky has gotten quite overcast with Orographic clouds as well as aerosols moving up from lower elevations. Wisps of fog and mist are beginning to blow through the science area, blowing up from the Saddle Valley. ___end___ **GENERAL PROBLEM COMMENT BY mcotter** : Sat Jun 04 23:15:55 GMT 2022 The dome shutter doors and windows have been closed due to overcast skies and fog in the science area. ___end___ Sun Jun 05 00:02:36 GMT 2022 UCoMP Restarted from pause GENERAL COMMENT BY mcotter: Sun Jun 05 00:05:22 GMT 2022 The day began with clear skies in all directions. By late morning some high altitude Cirrus was observed on the south-southwest skies. In the early afternoon Orthographic clouds blew up from the Saddle Valley and shortly later fog and mist arrived in the science area. ___end___ ONSITE STAFF: mcotter
