Blew off Kcor O1 for a bullet hole in the SW that I could see in the focus GUI, don't think it helped.

Washed Kcor O1 SN3 flushed and washed with soap. There was a feature towards the edge of the lens that required acetone to remove. Was flushed with water and rinsed again with soap to remove residue

Swapping Kcor O1-2 with SN3 for testing. Config file updated
___end___
** KCOR PROBLEM REPORTED BY berkey ** : Fri Oct 02 20:37:32 GMT 2026
During the instillation of the aperture  stop one of the fasteners slipped and landed on the glass and during the attempt to retrieve the screw if moved along the stop for a few inches.  It is not clear what this metal on glass contact did to the lens surface.

GENERAL COMMENT BY berkey: Fri Oct 02 20:39:24 GMT 2026
Clouds moved in after SN3 was fully blown off and installed in the telescope.  Visual inspection with sunlight shows significant improvement vs yesterday, but it will be difficult to get back to back data.

Washed Kcor O1-2 has been washed to address the three bullet holes in the West of the data that showed up during the swap yesterday.

Since clouds came in shortly after we swapped the O1's, KCor O1 SN3 has been removed from the instrument and O1-2 has been reinstalled with the config file updated to reflect O1-2 in the instrument. Clouds remain covering the sky at present, so not sure if the cleaning removed the bullet holes that were seen in O1-2 data.

Note that O1 SN3 has been put back in its case and put in a pelican case in the clean room.
