No wind. ___end___ GENERAL COMMENT BY mcotter: Fri Jul 03 16:58:14 GMT 2026 Opened windows upstairs ___end___ GENERAL COMMENT BY mcotter: Fri Jul 03 16:58:20 GMT 2026 Dome open ___end___ ** KCOR PM mcotter ** : Fri Jul 03 16:58:25 GMT 2026 Blew off Kcor O1 ___end___ Fri Jul 03 17:03:38 GMT 2026 Kcor Focus/alignment program exited KCOR COMMENT BY mcotter: Fri Jul 03 17:08:45 GMT 2026 Kcor: The Kcor cor instrument is now observing though the sky is slightly bright and some aerosols were visible in the Focus routine. The Focus was manually reset from 133.26 to 134.46. ___end___ ** KCOR PROBLEM REPORTED BY mcotter ** : Fri Jul 03 17:24:29 GMT 2026 Kcor circular acquisition error. Error began at 17:15:26 UT and went to 17:19:44 UT. Kcor is again observing and the Polarization looks good. ___end___ KCOR COMMENT BY mcotter: Fri Jul 03 17:28:03 GMT 2026 Kcor: Observations look good, but the sky is a bit bright and aerosols are heavy and prevalent in the images. ___end___ Fri Jul 03 18:17:04 GMT 2026 Report Time: 18:16:40 UTC Image: 20260703_174409_kcor_l2_nrgf.gif Obs time: 17:44:09 Launch Time: 18:06 CME Front Height: 1.40 Rs (front) CME Front Angle: 282.2 East Wing Angle: 265.9 West Wing Angle: 295.4 Angular Width: 29.5 CME Speed: fast CME Brightness: moderate Confidence: medium ** GENERAL PROBLEM REPORTED BY mcotter ** : Fri Jul 03 18:23:35 GMT 2026 After using the NRGF CME Viewer to report a CME the program froze up and was not responding. I closed the program and restart it and it opened with no problem and is now running normally. ___end___ Fri Jul 03 19:13:11 GMT 2026 Report Time: 19:12:52 UTC Image: 20260703_190805_kcor_l2_nrgf.gif Obs time: 19:08:05 CME Front Height: 1.50 Rs (front) CME Front Angle: 250.4 East Wing Angle: 242.0 West Wing Angle: 264.5 Angular Width: 22.5 CME Speed: moderate CME Brightness: bright Confidence: high Seen in: nrgf ** GENERAL PROBLEM REPORTED BY mcotter ** : Fri Jul 03 19:37:12 GMT 2026 After reporting a CME on the NRGF CME Viewer the program froze up and crashed. I had to close out the program and reopen to get it operating. The program seems to be be operating normally now, but the CME Launch reports that I am making on the NRGF CME Viewer ar not showing up in my email. ___end___ Fri Jul 03 20:03:01 GMT 2026 KCOR Start Calibration script: c:\kcor\mlso-calibration22deg-20171025.ini Fri Jul 03 20:17:58 GMT 2026 KCOR End Calibration Script ** GENERAL PM mcotter ** : Fri Jul 03 20:37:07 GMT 2026 At 10:00 am HST I noted the input for the Eco Flo Power Supply and the reading were as follows: Input: Approximately 920 W Output: Approximately 650 W As per Ben's previous action on the YETI Power Supply panels earlier this week, I brought the photovoltaic panels for the Eco Flo Power Supply to level with the ground. This has brought the panels more in line with the Sun's current path in the sky. After realigning the Eco Flo Power Supply panels the readings at 10:10 am HST were as follows: Input: Approximately 1090 W. Output: Approximately 650 W. An approximate increase of 18%. ___end___ Weather COMMENT BY mcotter: Fri Jul 03 20:41:04 GMT 2026 MLSO Current Weather Timestamp (UTC): 2026-07-03 20:35:00 Temperature : 54.57 deg F Dew Point : 35.83 deg F Pressure : 680.18 mbar Wind Speed : 9.17 mph Wind Direction : 320.8 deg Skies: Orographic clouds have formed and are now rising above the western slope of Maunaloa. The rest of the sky remains clear but aerosols are heavy. ___end___ Weather COMMENT BY mcotter: Fri Jul 03 21:24:51 GMT 2026 MLSO Current Weather Timestamp (UTC): 2026-07-03 21:20:00 Temperature : 52.95 deg F Dew Point : 36.12 deg F Pressure : 680.13 mbar Wind Speed : 6.71 mph Wind Direction : 18.4 deg Skies: The sky continues to be clear overhead but aerosols are very high. Orographic clouds are rising up over the eastern and western slopes of Maunaloa and moving toward the observatory. ___end___ Weather COMMENT BY mcotter: Fri Jul 03 21:51:47 GMT 2026 MLSO Current Weather Timestamp (UTC): 2026-07-03 21:47:00 Temperature : 52.86 deg F Dew Point : 39.57 deg F Pressure : 680.14 mbar Wind Speed : 3.36 mph Wind Direction : 342.3 deg Skies: Orographic clouds are moving in close from the west, north and east. For now the sky remains clear in the viewing area but aerosols are very high. ___end___ KCOR COMMENT BY mcotter: Fri Jul 03 21:56:31 GMT 2026 Kcor: The Kcor instrument is now paused due to clouds in the viewing area. ___end___ KCOR COMMENT BY KCOR: Fri Jul 03 22:45:24 GMT 2026 KCOR file transfer report KCor created 1318 .bin files 1316 .fts files NOTICE ? 2 .bin file(s) with no matching .fts: 20260703_171959_kcor.bin 20260703_223813_kcor.bin Remote site is complete ? no rsync required. ___end___ BY mcotter: Fri Jul 03 22:52:35 GMT 2026 End Of Day: The morning was clear and observations were good. Two CME launches were reported, but the Dusk computer is being worked upon so the observer initiated CME alerts did not go out on the email notification; I informed Ben of this happening. Clouds came into the viewing area at approximately 12:00 PM HST then it got completely overcast at approximately 12:30 PM HST. Happy Independence Day!! ___end___ Logger COMMENT BY mcotter: Fri Jul 03 22:52:40 GMT 2026 Log closed ONSITE STAFF: mcotter ___end___
