    Comments: 16:00 Hall in controlled access to change calorimeter angle, replace an ADC card, and a HV crate. 18:03 Start Optics run, C foils, I=40 uA. 18:09 Q1 quenched. Lost about 1 hr of good beam. Beam was available and on target but we could not take data. 19:04 LH2-No R target in place, e-p calibration runs started.
