Thunderstorms last night affected swing shift, followed by a 2K cold box trip, causing beam down for a while https://logbooks.jlab.org/entry/3818860

07:55 MCC did a harp fitting this morning https://logbooks.jlab.org/entry/3818888

08:02 Day shift expert noticed BONuS alarms were still disabled and reactivated them.

08:30 MCC calls to send beam to tagger dump. Day shift expert follows procedures and prepares for this. Solenoid and tagger ramped to nominal settings for BONuS12 calibration https://logbooks.jlab.org/entry/3818898
