During the last cleaning we noticed a residue on the back side of the O1 along about 1 " in from the edge spanning the region from approximatly S to NW. Today an attempt was made to clean the reside off with acetone; but this had no obvious effect. The (back side of the) lens was then cleaned with first contact. This again had no obvious effect on the reside. Finally an attempted was made ot rins the lens off with DI water as to best effort. The O1 has been reinstalled and hopefully we see some improvement. ___end___ GENERAL COMMENT BY mcotter: Thu Oct 28 03:29:46 GMT 2021 PM Washed Kcor O1.
