    Swing-shift summary

    16:00 : Ongoing Moller measurements
    16:58 : End of Moller measurement, call for controlled access to check calorimeter signals in two channels; found good pulser signals up to the detector hut. (Found in later analysis of run #1551 both blocks (31 &127) with good signal!)
    18:25 : Hall A beam permit
    18:30 : Asked for 30 uA unrastered beam on 12C.
    18:58 : Start 12C run - very unstable beam
    18:20 : 12C run gives very wide BPM 4B y distribution (run #1541)
    18:25 : start new 12C runs after accelerator tuning
    20:00 : BPM 4B y-distribution still > 0.7 mm FWHM, most likely moving beam.
    21:10 : no improvement on the beam quality; target change to 15 cm LH2
    21:50 : started 1H data taking (run #1551) with still very unstable beam conditions
