** GENERAL PROBLEM REPORTED BY mcotter ** : Sun Jun 14 17:18:06 GMT 2026
A had a difficult time connecting with Global Protect on the Wahoo 2 and Kcor computers. It took multiple attempts with each computer before it would latch on.

KCOR  BY mcotter: Sun Jun 14 17:52:08 GMT 2026
After starting Kcor observations I checked the polarization and it checked good (Mid, Bright, Dark, Mid). After approximately 10 to 15  minutes I saw an  irregular pattern in the Level 0 and NRGF images, additionally the bottom Synoptic pair of images showed a "Four Leaf Flower" pattern. I suspected that the Polarization changed state, so I again put the polarizer in the beam and the Polarization was bad (Dark, Mid, Bright, Mid). I stopped the observing code, re-homed the polarizer, then re-started the observing code. When the observing code Synoptic images came up I checked the polarization and it checked good (Mid, Bright, Dark, Mid).

The first bad polarization image that I saw in the Level 0 images was at 17:20:31 and the last bad polarization image that I saw in the Level 0 images was at 17:28:36.

The Kcor instrument is again observing. Polarization checked good.
