I tried restarting the monitor a couple of time and the restarting the splitter a couple of time but it did not work. Finally I power cycled the power strip and that did the trick and the monitor started working. ___end___ KCOR BY mcotter: Tue Jun 23 17:22:27 GMT 2026 Kcor: The Kcor instrument is now observing. Lots of aerosols visible in the Focus routine. I manually set the focus to 134.5 from 131.7. Polarization looks good. The synoptic images are a little bright, but they look good. Lots of aerosols visible in the Level 0 images and in the first couple of frames of the NRGF images. ___end___ ** KCOR PROBLEM REPORTED BY mcotter ** : Tue Jun 23 17:42:27 GMT 2026 Kcor circular acquisition error: Polarization turned bad. When looking at the Level 0 image it started at 172849 and continued to 173207, with poor data continuing until 173636 as I restarted the instrument and again cycled the optics. ___end___ KCOR BY mcotter: Tue Jun 23 17:43:40 GMT 2026 Kcor: Kcor is again observing, but aerosols are quite visible in the images. ___end___ Tue Jun 23 18:51:41 GMT 2026 Report Time: 18:49:49 UTC Image: 20260623_183214_kcor_l2_nrgf.gif Obs time: 18:32:14 Launch Time: 18:23:14 CME Front Height: 1.86 Rs (front) CME Front Angle: 69.1 East Wing Angle: 51.2 West Wing Angle: 92.1 Angular Width: 40.9 CME Speed: fast CME Brightness: bright Confidence: medium Weather COMMENT BY mcotter: Tue Jun 23 19:03:14 GMT 2026 MLSO Current Weather Timestamp (UTC): 2026-06-23 18:56:00 Temperature : 55.35 deg F Dew Point : 25.36 deg F Pressure : 681.47 mbar Wind Speed : 9.17 mph Wind Direction : 0.3 deg Skies: The sky overhead appears bright but clear.

I went to the dome and there was no problem with the dome. I tried stopping the observing program and a GUI came up telling me there was an error with socket cam. I tried to restart the program but the GUI came up again. I restarted the computer but the Socket Cam still would not work and a GUI came up stating there is a problem. I took screen shots of the GUI's and emailed them to Ben and Lisa. I texted Ben to call me and he called me back and told me to check the "E" Drive to see how much disk space was available, as this is where the socket cam puts it's data. There was 0% disk space available. Ben told to delete the oldest file, which I did. Then I restarted the Kcor observing program and socket cam worked fine. ___end___ Weather COMMENT BY mcotter: Tue Jun 23 23:35:01 GMT 2026 MLSO Current Weather Timestamp (UTC): 2026-06-23 23:29:00 Temperature : 62.37 deg F Dew Point : 31.04 deg F Pressure : 680.79 mbar Wind Speed : 12.75 mph Wind Direction : 62.0 deg Skies: Orographic clouds have move in over the observatory from all directions. ___end___ GENERAL COMMENT BY mcotter: Tue Jun 23 23:35:30 GMT 2026 Dome closed.
