Yesterday we didnt hear anything from MMC till mid night. From the log entires we could see, they had problems with the beam transport
* MCC called CH for access to the hall to reboot the IOC. SL Vidura had to access the hall in Radcon personal presence and could hard reboot IOC. Later went to beam permit.
* At 01:20 - MCC called in to send the tune beam in to the hall. They had hard luck to fix harps till 7:00 in the morning.
* MCC could copmlete harps and narrowed down beam size at Targ. to  X = 0.505577,  Y = 0.381809 (https://logbooks.jlab.org/entry/4371885)
* SL Kondo and Jivan could finish beam recovery by 12:20.
* Jiwan needed an escorted acces to the hall to replace one of HCAL flash ADC module
Hall A: There was access to Hall by GEM, ECal, CDet, Target groups and they accomplished their work by 13:30.
Target: Cryotarget Loop 2 temperature read-back failure, later it was recovered (https://logbooks.jlab.org/entry/4370932 , https://logbooks.jlab.org/entry/4370967)

There was no plan to access the hall from any subsystem, we requested techs for SBS magnet power box to unlock (https://logbooks.jlab.org/entry/4370955). MCC was request to put hall in power permit. We are still in controlled access.
