8:00-10:05 Runs 2249-2250. Finishing data taking at x=0.48, transverse pol. (270 deg), beam lambda/2 OUT.
10:05 Changing to BeO target. Spectrometers to 1.32 GeV/c.
10:10 Left arm Q2 quench.
10:50 Quench cleared. Right arm dipole still settling, so no time lost.
11:13 Start run 2251/21251 on BeO/carbon, no raster, 5uA, for pointing
11:50 Start data taking with BeO/12C, raster on, 25uA, false asymmetry checks
ca. 15:00 Notice much increased value of charge asymmetry (-1789ppm). Apparently the value started rising around 14:00. Bob Michaels investigating.
