9:32UTC LOCKLOSS

Rather random lockloss because environmentally we were quiet quiet.  lockloss2 script has a few possible lockloss candidates and the SRM seems to be the most obvious reason for a lockloss as several SRM channels ramp up just prior to the lockloss.  Ther were also some MICH signals getting noisy as well.  PRM also has similar ring up like the SRM.

As for getting back to OBSERVING, basically made it back UP in 33min.  Here are some notes from locking.

• For the ALS Green Arms, I tweaked up the TMSx & y to raise up the powers.
• Then the usual aligntment tweaks for ETMs, BS, & PRM
• Once at NLN, had PLC2 Diffs at the CS & EY (attached).  Accepted both which were:
  • H1:ALS-C_LOCK_REQUESTY (for H1SYSECATC1PLC2):   was "Red Locked" & now "End Locked"
  • H1:ALS-Y_LOCK_STATEMENT (for H1SYSECATY1PLC2):  was "Red Locked" & now "End Locked"
