H1 abrubtly dropped out of lock.  Did not see any obvious reasons for why at first, but then while waiting for Guardian to bring us back, noticed that we have no light from the PSL.  

IMC_LOCK Guardaian is saying:  FSS Unlocked.  (Looking for instructions/alogs about how to address this).  

But I also see that we have 0W output power for the Laser.  Might go to the Laser Diode Room to see if there are any obvious messages.

There is no light on the PSL video screens.

Talking with Jason right now.
