The image did not change. I waited until after 9:00am HST and ran another calibration. I paused Kcor, went back and ran the Focus routine again. I obtained a decent parabola, then checked the polarization image, as Lisa showed me, to see if the four Kcor Stand Alone Acquisition images came up properly. With the Diffuser and Polarizer lenses in the images appeared from top to bottom MID, BRIGHT, DARK, MID. The Kcor image now appears to be correct. ___end___ GENERAL COMMENT BY mcotter: Sat Oct 24 20:01:10 GMT 2020 While running the Focus routine lots of aerosols can be observed in image. ___end___ GENERAL COMMENT BY mcotter: Sat Oct 24 21:03:20 GMT 2020 Cirrus clouds forming and increasing over the observatory. Pausing Kcor. ___end___ GENERAL COMMENT BY mcotter: Sat Oct 24 21:31:03 GMT 2020 Cumulus clouds forming to the South and increasing. Tried restarting Kcor, but increasing clouds forming over the summit required me to shutdown again after just a few minutes. ___end___ GPS COMMENT by MLSO: Sat Oct 24 21:45:11 GMT 2020 Successfully logged in to system Good disk mount GPS software running Last 5 GPS data files are: /mnt/usb/dataoutiq_2020_293_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_294_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_295_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_296_2145.bin 2147483647 /mnt/usb/dataoutiq_2020_297_2145.bin 2147483647 Disk usage: /dev/sda1 916.9G 189.6G 680.6G 22% /mnt/usb ___end___ GENERAL COMMENT BY mcotter: Sat Oct 24 22:13:30 GMT 2020 Dark gray Orographic clouds have come up from the east and have combined with the Cumulus clouds from the South.
