----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Tue Jul 6 16:46:01 GMT 2021 Year: 21 Doy: 187 Observer: mlso WEATHER COMMENT: mcotter: Tue Jul 06 16:50:31 GMT 2021 Temp: 51.1f, Humidity: 22%, Pressure: 28.678in, Wind: 4mph from 120degs, Skies: Heavy cloud coverage in the Saddle Valley with fog, rain and mist to approximately 8,500' elevation. Hazy skies with high altitude Cirrus and Cirrostratus clouds covering the entire sky. ___end___ GENERAL COMMENT BY mcotter: Tue Jul 06 16:52:21 GMT 2021 The Current sky conditions a poor and we are unable to operate the instruments at this time. The dome will remain closed until conditions improve. ___end___ GENERAL COMMENT BY mcotter: Tue Jul 06 18:02:19 GMT 2021 Opened windows upstairs ___end___ GENERAL COMMENT BY mcotter: Tue Jul 06 18:02:29 GMT 2021 PM Blew off UCoMP O1 ___end___ GENERAL COMMENT BY mcotter: Tue Jul 06 18:02:35 GMT 2021 PM Blew off Kcor O1 ___end___ Tue Jul 06 18:10:03 GMT 2021 Kcor Focus/alignment program exited GENERAL COMMENT BY mcotter: Tue Jul 06 18:16:44 GMT 2021 The bands of high altitude Cirrus and Cirrostratus clouds are still quite prevalent across the sky but they have faded somewhat and there appears to be band of blue sky intermixed with the clouds. I opened the dome. ___end___ KCOR COMMENT BY mcotter: Tue Jul 06 18:22:15 GMT 2021 I started Kcor and ran the focus routine. The sky is still very bright but after many attempts I was able to obtain a reasonably well shaped parabola. I attempted to start running the Kcor Stand Alone Image Acquisition (SAIA) program but the sky remains much too bright at this time to run the instrument. ___end___ UCoMP COMMENT BY mcotter: Tue Jul 06 18:25:01 GMT 2021 I started the Ucomp Controller program but when I switched to Center Occulter the image immediately became over saturated with light. The sky remains mush too bright at this time to run the instrument. ___end___ KCOR COMMENT BY mcotter: Tue Jul 06 19:11:16 GMT 2021 Kcor up and running. SGS offsets: X(RA): -130, Y(Dec): 90. Polarization checked good: Mid, Bright, Dark, Mid. ___end___ UCoMP COMMENT BY mcotter: Tue Jul 06 19:11:40 GMT 2021 Ucomp up and running. ___end___ Tue Jul 06 20:00:04 GMT 2021 Kcor Focus/alignment program exited WEATHER COMMENT: mcotter: Tue Jul 06 21:17:45 GMT 2021 Large bands of Cirrus and Cirrocumulus clouds have moved in from the west-southwest and are now covering the sky above the observatory. The wind is light and out of the north-northwest. Orthographic clouds are currently forming on the northwest slope of Maunaloa. ___end___ KCOR COMMENT BY mcotter: Tue Jul 06 21:18:38 GMT 2021 Kcor has ben stopped for now because of cloud coverage obscuring the viewing area. ___end___ UCoMP COMMENT BY mcotter: Tue Jul 06 21:19:24 GMT 2021 Ucomp has been paused for now because clouds are obscuring the viewing area. ___end___ WEATHER COMMENT: mcotter: Tue Jul 06 22:47:14 GMT 2021 The sky continues to be completely covered with Cirrostratus and Cirrocumulus clouds. Clouds are continuing to increase in coverage and Orthographic clouds have increased on the northwest slope of Maunaloa and are beginning to encroach on the observatory area. ___end___ GENERAL COMMENT BY mcotter: Tue Jul 06 23:13:50 GMT 2021 The sky continues to be overcast with high altitude Cirrus and Cirrostratus. Orthographic clouds are nearing the observatory and increasing. The dome shutter doors and windows are closed at this time. ___end___ ONSITE STAFF: berkey, mcotter
