Atleast half of the shift had H1 at Nominal Low Noise!

Day's Activities:

• Walked in to a locked (~8+hrs) H1.  
• Robert went out for Acoustic Injections, H1 dropped dropped shortly after (due to PI most likely).
• 12:25: Injections (Robert)
• 12:40:  Hanford Site Alarming Test phone call
• 12:43:  Working on DIAG_CRIT
• 12:50:  EY & EX Hartman code work (Carlos P)
• 1:17 MYparts for squeezer (fil & mark)
• 1:42-2:58 Scroll pump reassembly & CP3 overfill (Kyle)
• Addressed (1) Remote Access request.

Locking Notes:

After the long lock this morning, H1 was stuck at CHECK_IR.  Adjusted COMM OFFSET, but could only get the X-arm up to 0.5; during one attempt the XARM gain was oddly at 0(!).  Opted for an Initial Alignment.

INITIAL ALIGNMENT notes:

At ALIGN_PRM, AS_AIR video looked ugly & would not lock up.  Errantly moved PRM & PR2 to a time during the long lock....but this cancels the INPUT_ALIGN pointing we had (!).  Kiwamu returned PR2 to it's aligned value and then continued with Alignment.

Ops Locking Note: (OpsInfo!)

I didn't get to all the alogs over the weekend.  Jenne filled me in on a new Guardian state (CHECK_MICH_FRINGES) for those times when you are locking DRMI and alignment looks bad/ugly & when there is hardly any flashes.  CHECK_MICH_FRINGES allows you to optimize your BS alignment for DRMI locking.  Please see Jenne's alog & also the new entry in the Ops Sticky Note wiki.
