TIME: 17:12:09 UT PA: 245 deg WIDTH: 40 deg This CME was in progress when the observer signed on this morning and began taking data. This CME is in an area of the Sun that has shown elevated activity for the last several days. ___end___ Mon Aug 29 18:04:36 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 0 GENERAL COMMENT BY mcotter: Mon Aug 29 18:14:02 GMT 2022 PM Blew off Kcor Field Lens. There appeared to be an artifact in the Kcor NRGF image at approximate PA 120 degs. The artifact appears to have been removed after blowing of the Field Lens. ___end___ Mon Aug 29 18:41:04 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 20 KCOR COMMENT BY mcotter: Mon Aug 29 18:41:25 GMT 2022 A very large prominence is currently visible in the Kcor NRGF image at approximate PA 165 degs, with a width of approximately 50 degs. The prominence is so large it can be observed in the Kcor Synoptic Level 0 images. ___end___ Mon Aug 29 18:44:26 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 21 Mon Aug 29 18:44:27 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal.cbk line 0 Mon Aug 29 19:22:39 GMT 2022 Running UCOMP Cookbook all_wavelength_coronal_flat.cbk line 0 Mon Aug 29 19:43:15 GMT 2022 Running UCOMP Cookbook waves_1074_1hour.cbk line 0 ****CME Retraction BY mcotter**** : Mon Aug 29 19:55:15 GMT 2022 CME at A CME event was reported by the automatic detection system that the observer cannot confirm. According to the auto-detection system a CME was reported at 19:13:23 UT, at PA 244.5 degs. While this area of the Sun has been quite active, and a CME was reported earlier today in that same location, the reported CME at 19:13:23 UT cannot be corroborated with the data taken. Aerosols are beginning to get heavy, so it is possible that the auto-detection system may have observed an aerosol in the data stream and mistaken it for an actual CME event. ___end___ Mon Aug 29 19:59:10 GMT 2022 Running UCOMP Cookbook waves_1074_1hour.cbk line 28 Mon Aug 29 20:01:49 GMT 2022 KCOR Start Calibration script: c:\kcor\mlso-calibration22deg-20171025.ini Mon Aug 29 20:02:29 GMT 2022 Running UCOMP Cookbook waves_1074_1hour.cbk line 32 Mon Aug 29 20:06:26 GMT 2022 Running UCOMP Cookbook waves_1074_1hour.cbk line 37 Mon Aug 29 20:17:00 GMT 2022 KCOR End Calibration Script WEATHER COMMENT: mcotter: Mon Aug 29 20:26:18 GMT 2022 Aerosols are getting heavy and are quite visible in the Kcor NRGF and Quicklook images. ___end___ Mon Aug 29 20:45:04 GMT 2022 Running UCOMP Cookbook waves_1074_1hour.cbk line 104 Mon Aug 29 20:58:29 GMT 2022 Running UCOMP Cookbook dark_80ms_2beam_16sums_BOTH.cbk line 0 Mon Aug 29 20:59:46 GMT 2022 Running UCOMP Cookbook 637_Pol_Calibrate.cbk line 0 Mon Aug 29 21:03:50 GMT 2022 Running UCOMP Cookbook 706_Pol_Calibrate.cbk line 0 Mon Aug 29 21:07:55 GMT 2022 Running UCOMP Cookbook 789_Pol_Calibrate.cbk line 0 Mon Aug 29 21:12:08 GMT 2022 Running UCOMP Cookbook 1074_Pol_Calibrate.cbk line 0 Mon Aug 29 21:16:43 GMT 2022 Running UCOMP Cookbook 1079_Pol_Calibrate.cbk line 0 Mon Aug 29 21:20:16 GMT 2022 UCoMP Paused for clouds WEATHER COMMENT: mcotter: Mon Aug 29 23:34:04 GMT 2022 It is now totally overcast with dark gray clouds. Bits of fog and mist are beginning to encroach on the science area. The dome has been closed due to poor weather conditions. ___end___ Tue Aug 30 02:01:53 GMT 2022 UCoMP Restarted from pause GENERAL COMMENT BY mcotter: Tue Aug 30 02:03:47 GMT 2022 The day started clear but a bit hazy. A nice CME was observed in progress when observing began this morning but by late morning clouds and aerosols made their way to the observatory and observing was soon halted for the day. ___end___ ONSITE STAFF: mcotter
