We lost lock because of PI 24 in our last lock.  We are also seeing a correlation between PI channels and loud glitches in H1 (Derek made some nice plots in 82961).

We've stepped up the EY ring heater both upper and lower segements from 1.2W to 1.3W.  This has been stepped up in Decmeber 81890 81891 and September 80320.

We did the step after Corey had the IFO locked with all ASC on, to deal with the alignment shift after this lockloss we will probably need an initial alignment.
