Sad thing though, I should have realized, the decline of the driftmon now puts the camera image in jeopardy of being too close to the edge. I had the enclosure open for a time and the cool down has pulled the drift signal down to -15660. It could be 24 hours before things warm up enough to bring it back to before incursion level of -14000.
Ed has the BRSY engaged to nominal now but we are watching to make sure it is doing some good for the IFO.
We'll need to make another centering effort within a couple weeks.
