H1 had a lockloss after about 3hrs (no notable reason).  NOTE:  ITMy Mode5 was taken to it's nominal gain of -0.04 by the VIOLIN DAMPING guardian when it was locking early this morning during the OWL shift. 

Looking at ITMy's Mode 5 for the last lock, it looked like the slope for mode 5's ringing up was slightly higher/steeper with the -0.04 gain, so I am taking it back down to the non-nominal -0.02 gain Rahul & Tony had been using for the 500Hz violin mode recovery/ring down. 

H1 went down at 1635utc & was back to Observing at 1745utc.
