00:00 Begin shift with detector checkout.

03:05 Access complete. Ask for beam permit.
03:15 Beam back into the hall. Resume detector checkout.
03:51 No beam due to MCC IOC problem.
03:54 Beam back and resume detector checkout and HV matching for left HRS.
05:45 Completed left HRS S1, S2m and gas Cerenkov alignment.
Could not align pion rejector, since the cable map is wrong!
05:48 Move target to holey carbon for beam position and raster check.
06:53 MCC called beam will be away in 5-10 minutes for them to address a magnet problem.
06:45 Noticed that left Q1 had tripped off around 5:45. We did not
notice since the alarm handler was not enabled and we were doing
beam position scans.
Nominal BPM positions:
BPMA: (-2,1.25)
BPMB: (-3,1.5)
07:08 MCC called magnet repairs are being put off until the downtime later this morning.
