00:13 beam back, but some spills 'missing'

      DESPEC keeping beam as is, but may stop later if it worsens

      FEE64 module aida07 failed
      FEE64 module aida10 failed
      Calibration test result: Passed 10, Failed 2

      If any modules fail calibration , check the clock status and open the FADC Align and Control browser page to rerun calibration for that module

      aida12 fault 	 0x0 : 	 0x1 : 	 1  
      FPGA Timestamp error counter test result: Passed 11, Failed 1

     If any of these counts are reported as in error
     The ASIC readout system has detected a timeslip.
     That is the timestamp read from the time FIFO is not younger than the last

00:24 still no bad timestamp errors in NewMerger since 16:30 UTC
