16:20-30 did a quick harp scan test. However, forgot to end run 2564. 16:30 back to normal production running. The beam current is 26 uA instead of the 35 uA we asked.
16:50 spot move to increase the current to 35uA; stop and restart both parity and compton runs;
17:50 zero Hall C asymmetry during run 2566, new IA point 1.565
21:49 lost lock for Right arm Q2 and Q3, reset IOC, see 127559
22:52 Right arm magnets recovered;
23:15 Found we lost IOC for both septa, see 127561; it must have happened when we reset the right magnets IOC. Too bad we didn't notice it until now. => reset septa IOC => need to reset from downstairs => tech on call is coming in;
23:30 Hall in controlled access;
Accumulated charge of this shift: 0.498 C (two arms)
