  1. Accelerator Status over the last 24 hrs
    • Accelerator busy with Hall C until 05:00
    • Hall D first given beam at 05:20
    • Data collection at 50nA started at 08:00
  2. Hall-D/GlueX items
    • In the last 24 hours:
      • Low-intensity production started at 08:00
      • Long mode run (10 minutes) done at
      • Current Total: 40.05B
  3. Issues
    • DAQ issues:
      • 5:42 - The DAQ keeps giving us "SEBO: Client has not reported for xx sec." errors, but then recovers after a minute. This happens every ~20mins or so. We will restart the DAQ again after the current run finishes.
      • ~22:00 - Monitoring stops working, have to start/stop runs several times to get events flowing through secondary ET
  4. Monitoring
    • low-level report
  5. Run Plan
    • Production
    • Triggers: In-time random? Min-bias? FCAL+BCAL+ST?
  6. Offline Analysis
    • TAC runs?
