Comments: 

Engineering DECam night.

Running on all the 6  new readout machines. Today we ran 600 zeros + the calibrations.  At the end of this we had a backplane 4 failure.  It did take a SISPI restart to recover.  Marco made some change to the computer and he did capture what the fault was caused by. Everything else looked good, guider and the AOS worked. Several 500s exposures taken through N673, got sub arc sec images perfectly round.

Second half -- good performace of DECam and great seeing. Testing with Science.
