We checked imaged biases twice, left part of CCD33 (u' at id3) eally has bias level different from all others. Bias level is ~2600 at the left (bad) part, and ~1200 at the right (good) one. We notified Connie and Jim by e-mail, talked to Connie, took bias with t-bars unlatched. With t-bars unlatched is was getting better (finally 1320 against 1250), and then , with t-bars latched back it didn't show significant difference between left and right parts of CCD33. --- failed to take semMEI: S objLib OBJ TIMEOUT (3997700) (2008-01-15 01:04:45Z sdssmcp) (failed to take semMEI: S_objLib_OBJ_TIMEOUT (3997700) (2008-01-15 01:04:45Z sdssmcp): 2008-01-15 01:04:57Z ) Checked, pointed again, no problems found, the error didn't come for the second time. ---
