It is horribly painful to make this aLOG entry from the control room as there is a constantly repeating voice simulation alarm "gamma ray Burst...gamma ray burst...ga"!  HELP! I do anything - just make it STOP - PLEASE, I"m begging you!

The Vertex MTP and scroll are quiet and happy.  As found, the LVEA lights were on so I turned them off as I left.  Much to my surprise the main entrance door is properly locked!  The included plots show that the HAM11 AIP has blown up again.  Both the pump and controller have been replaced within the past 14 months or so. 

2150 hrs. local -> Kyle leaving site now.

Sorry about this, Kyle.

I don't have remote access to acknowledge the alarm. Since we do not have operators on shift, I suggest we do one of the following when we don't have 24/7 coverage:

Turn volume down on the Alarm computer (easiest and Monday morning operator will turn it up)
CTRL-C out of the VERBAL ALARM terminal (to completely close the VERBAL ALARM)
Or to acknowledge the alarm, I believe the VERBAL ALARM says to type "yes or no"
