In Restricted access at shift start
Plan is to take data (kin 3) when we get beam back
Left HRS 31.819 degrees 1.494 GeV/c
Calorimeter 14.78 degrees
19:06 Called for a sweep of the Hall.
Sometime after 20:00 in controlled access
Alex and Carlos still testing DAQ at 20:23
21:30 Beam back doing beam checks
Harp scans look good A sigma_x= 0.1594 y=0.1136
B 0.1524 0.1698
22:00 Moving to LH2 target
(turn fan speed on loop 2 back up to 46 Hz)
