1. Past 24 hours:
   • Acceptable quality beam established early morning around 11:00 am.
     • Beam profile and convergence by Jay:https://logbooks.jlab.org/entry/3652506
   • DIRC data taking.
     1. DIRC analysis is on-going.
2. Issues
   • Cryo Water Temperature jump to 72F (limit 70F).
     • Due to pump switch: https://logbooks.jlab.org/entry/3652512
   • IOC lost communication
     • IOCHDCOL failed at 21:30. Reported to us by MCC at 0:00. Reset at 1:50 am. Hovanes verified things are ok at 3am. https://logbooks.jlab.org/entry/3652920
   • DIRC SSP problem:
     • DAQ stopped twice due to the out of sync issue.
   • Tagger RF time: https://logbooks.jlab.org/entry/3652533
   • hdview2 is work working
3. Today:
   • No planned access
   • Opportunistic access requested by Kenoe to work on GEM.
   • DIRC nominal running (MOROC threshold scan?)

1. Past 24 hours:
   • Nominal DIRC setting collected 1B triggers, switching to the higher MOROC threshold (200)
   • Smooth overnight running at 180nA, coming back to the desired 225nA this morning.
   • Both opportunistic accesses happened during the accelerator down time due to the bulk power supply failure.

1. Issues:
   • Beam steered to the wrong BCM, therefore constrained the maximum beam delivered to 180nA
   • Goni camera, wrong angle, did something move?
   • root spy crash
   • DIRC SSP out of sync over night (after switching the MOROC threshold).

1. Plan for today:
   • keep collecting higher MOROC threshold data (up to 1B triggers).
   • When beam is not available, 15 min LED runs with different pulsing and trigger conditions.
