  • 17:30 UT - Delay difference is higher than normal, ~0.5 us, however it is sitting stable at this delay so I have left it be. (Tiege)
  • 18:30 UT - Experiment started late, during first scan sync error developed, halted schedule, first valid scan is 252-1840. This also has fixed the larger delay. (Tiege)
  • 23:10 UT - Delay difference falling off consistently though linearly. Rate has now begun to steepen over last few scans with alarm triggered (Ross).
  • 23:40 UT - Delay difference following new linear fall off, but so steep it will exceed 1ms by end of experiment. dbbc restarted. Missed scans 252-2341b and 252-2348b (Ross).
