Once we flipped them back over and checked the wiring, we got back those watts. ___end___ Sun May 24 00:24:25 GMT 2026 KCOR End Patrol KCOR COMMENT BY KCOR: Sun May 24 00:25:21 GMT 2026 KCOR file transfer report KCor created 1791 .bin files 1790 .fts files NOTICE ? 1 .bin file(s) with no matching .fts: 20260524_002432_kcor.bin Remote site is complete ? no rsync required. ___end___ GENERAL COMMENT BY lisapg: Sun May 24 00:29:30 GMT 2026 Dome closed ___end___ GENERAL COMMENT BY lisapg: Sun May 24 00:30:26 GMT 2026 A bit bright at the start of the day and the aerosols got have after 10 am HST but it was a nice day to take data!
