16:00-19:30 Smooth production running. Compton runs in parallel.
19:30 Beam goes away for Hall B tuning. ETA "30 minutes".
21:00 Beam finally returns. As we try to start the Happex DAQ, we get timeouts from the ROCs. Reboot ROCs, restart CODA.
21:10 DAQ is back up. Resuming production.
22:10 After run 12980, we ask MCC to take the IHWP out. Unfortunately, we forget to end the Compton run and to run flipper. Fortunately, we notice this within a few minutes. Restart Compton run, leaving a note in the logbook that the last few minutes should be discarded.
22:17 Run flipper after run 12981. 12981 is lunk. The data have the wrong slug number.
22:18 Start Happex run 12982, now with correct slug number = 19, IHWP = OUT.
23:13 End run 12983. Running spot++, left HRS run number 24974. Looks fine. Spot size ~6x5.5.
23:26 Resuming Happex production, run 12983.
24:00 Shift ends
