This seemed to have some improvement, but unlike in the videos from first contact the oring still pulled up and some matrial got stuck. During the first contact removal some sections ripped requring the O1 be cleaned to remove this residue. The O1 is now mostly clean of visible residue, but we are now low on power due to the rain. Pausing for now with the plan to finish the cleaning tomorrow. ___end___ Weather COMMENT BY berkey: Fri Jul 10 00:51:41 GMT 2026 Cirrus gave way to low clouds and eventually rain since about 12:30pm.
