Night Assistant:

Also Present: 
Hernan Tirado
Problems: 

Computer crash around 1am. First Confort display froze, then files were not successfully transferred.  Tried to reset master console, but that failed. Reconfigure failed.  Hernan was able to log in with an instrument account and reset the OCS. No subsequent issues.

Comments: 

The barking dog associated with Alarms at 'large' offsets is back. Sporadic bright lights shining from below off the summit onto (and into) dome from the east. We did not isolate the cause and they stopped at midnight. There are a few light pollution brochures in the console room if needed.

A good night overall.
