Problems: 

1.   The GPS-TCS insisted it was 2013 and not 2014.  After some time reting to fix it, Rolando hardwired the TCS to 2014.  We all felt old again.   To be fi
xed before Jan 1 2015.

2.  We had an alarm from the LN2 sytstem, the first at 1:25 am.  The differential pressure did three very fast up and down spikes to about 40 psi.  The third spike was so fast it generated no phone call.   There was no obvious correlation with any other event at the time, and in particular, I was looking at the pump speed when the third spike occurred, nothing happened.   Howver an hour later it was obvious that the LN2 use rate has drastically increased.  Nothing obvious, but TELIOPs should inspect the system asap in the morning to look for any leaks.   JIRA written

3.  The other problem was clouds, that were quite thick for the first thee hours, then better, but still hung around all night.

4.  And RASICAM appers to have the BB not working.  It's controller appears to be alive.  David suggested to power-cycle the whole system, but checking whether the BB is getting power would also be good to do, it is quite accessible.   All the builders, - Kevin Reil, Peter Lewia, Rafe Schlinder gave input.

5:  Please turn on the sound for observer1.  No beeps etc.
