    Comments: Beam available at start then HMS dipole trip. At some point around 8:15 energy change for Hall B began without notification. Asked for an access. After hall B energy change Hall A tuning for the Compton began. MCC called us at 10:45 to lock up but our guys were backing out of hms hv work. Locked up at 11:05am. Beam back at 12:10pm. Took a little data then DAQ hung up. Made an entry to power cycle fbhms. Restoration of beam took a bit.
