Difficulty Locking due to Violin Modes

S Dwyer, T Vo

Last night we tried locking for several hours, the violin modes were rung up from the 5.3 earthquake in Soda Springs, Idaho so it took a while to damp them by hand and wait for them to ring down.  Then we had a lock loss when going to DC_READOUT and this rung the modes up even more.  When we have the full IFO back, we will try to lock again.
