Bruce noticed at 4:40 PM that the SHOTS variable in housekeeping data had slumped. It should be running around 170. Very interestingly went from 168 to about 84: a perfect halving and did so in like a tapered cosine over the course of 2 hours.
He couldn't get LabVIEW to restart so had to reboot the data system. Upon restart it forced a scheduled increase in the flashlamp voltage to 1.50 kV.
This caused the 1064 and the 1543 energies to be a little higher than recommendations so he restarted it at 5:50 PM PDT with 250 millisecond q-switch delay (with 5 min warmup).
