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. Again we have problems with "fiducial reading" first time occured: Aug 27 22:34:37 sdssmcp tLatch dsc_I_trcInfo Applying correction 3859286 to azimuth Aug 27 22:34:37 sdssmcp tLatch dsc_E_trcErr correction for azimuth 3859286 is too large Aug 27 22:34:37 sdssmcp tLatch dsc_W_trcWarn Not disabling MS.ON; error 3859286 (max allowed: 600) and later. And we keep ignoring: 0 0 I Received="?GOCORR one or more axes did not end on a full step 0, 0, 0, 0, 1" 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.
