This afternoon we got a little more time with the IFO.  We redid inital alingment and were able to engage the ASC which increased our recycling gain.  We were able to power up to 15 Watts without a problem, when we increased the power to 23 Watts a 0.4 Hz oscillation that showed up mostly in SRC1 PIT and SRC2 PIT knocked us out of lock.  We've had difficulty in the early part of the evening with ALS, we have the glitches that show up in the arms even when only the arms are locked, reminding us of the glitches seen in alogs 17576 and 15242.  As before, these glitches went away a couple of hours and we are now locking OK again.  

We have reduced the time for the REFL trans ramp from 5 seconds to 1 second, this seems to be fine and we could think about making it shorter or reducing other ramp times in the final stages of CARM offset reduction.  We haven't had the REFL trans lockloss today, but this problem has always been intermittent so we will have to continue locking for several days to see if speeding it up actually helped.
