18:50 Ready to open. Some clouds at the Sun set but moustly blue sky. Cart 2 plt 634 on the telescope. 20:05 Ready to go. 20:50 An fk5 star found with no problem using the last night offsets. Again the seeing is very bad from 2.5 - 4.0", 3.5 m telescope observrs reported seeing about 4". The fficiency read from the guider: ~25%. There are thin clouds around, and we are collecting noise, so we decided do postcalib and no smearing. 22:45 Cart 9 plt 644 on. We didn't find stars with go to field, but we've found quickly fk5 star in a fiber. The seeing is getting better! However wind and its speed remain the same... The efficiency is high over 60%, but we've got very low S/N. Perhaps the sky brightness is too high? 23:30 Thick clouds are comming.
