      • No beam 4pm-11pm (lost vacuum in Hall C transport [1])
    • Saturday:
      • Goniometer stopped moving sometime between 5am and 3pm. The problem was only noticed at 3pm [2]. As a result, a few runs have unknown diamond orientation [3],[4]
      • Repair work on goniometer from 4pm till 7pm (no beam) [5]
    • Sunday:
  2. Changes
    • Change in TPOL readout [6], [7], [8]
    • New DIRC SiPM TDC reference timing [9]
