Walked in to a locked H1 and several tests going on.  After a while H1 dropped out & then Daniel/Keita ran some ISS arm power scaling tests.  

After these tests I wanted to get H1 locked up at High Power.  Similarly to last night DRMI & PRMI locking looked quiet.  So I went & used Sheila's trick of pushing the BS (see note in her alog about this & how to end the excitation).  This seemed to work in that PRMI was able to lock up...but I also tweaked the BS to bump up the PRMI flashes.

Took H1 up to INCREASE_POWER (I assumed it would take H1 to 30W, but it actually kept on going....at around 54W, I went ahead and selected 50W.).  I kept H1 at 50W for some high power locking.  Here are some notes from the lock thus far:

• After a few minutes, the PI MODE27 rung up, but it went back down without any action.
• MODE26 slowly started to ring up.  Since I had never dealt with PIs before, I grabbed Kiwamu for help.  This mode was using PLL to damp the mode.  When we looked at the mode, it wasn't large enough to lock the PLL so it could damp it out....BUT, Kiwamu noticed that if the PLL were to lock it up, it would excite the mode, because it had the wrong sign (+1.00).  Kiwamu changed it to -1.00 and then this damped out (after a quick test which Kiwamu showed me regarding the sign).
• MODE25 & MODE17 then rung up.  After some sign changes, Kiwamu determined that MODE17 did not have a small enough band pass & was observing crosscoupling from the true culprit:  MODE25.  Kiwamu worked on damping this guy out, but then we lost lock surprisingly (we had been noticing AS90 drifting down over our 90min lock.

FOM/Nuc5 Note:

I tried to fix nuc5, but after reboot, the seismic DMT viewers  were not getting data from correct time.  Is this a kerberos ticket issue?  Do we have instructions on this?

Seismic Config Note:

EX was taken to Windy NO BRS because Nutsinee was going to go in the VEA & just wanted to be safe.  EX ISI was returned to Windy config after she exited the VEA.  In hindsight, looks like we didn't need to do anything (her incursion wasn't seen on the STS).
