              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had the vertical bright region problem  with ecam and we were forced to pause an exposure so I could address the issue.  I tried a hub startNubs but it didn't help.  I power cycled the ecam from obs 1 and then did another nubs restart and everything worked.  We lost about 5 min.  The problem started with ecam image 750.
Dcam also had a readout issue but the targets were, thankfully, bright enough that we didn't have any guide problems.
The weather was beautiful all night and we had good seeing.
