long range actuator motion
Not that it is a concern but attached is a plot of the Long Range Actuator (LRA) position versus the
laser room temperature. I only note it because the 32 micron travel is perhaps the longest I've seen
it move, and represents 64% of the available travel before a PZT reset.
The data dropout corresponds to the DAQ restart at 23:02 UTC yesterday.

Heat was increased into the LVEA on Wednesday morning - it would be interesting to see the correlation with the increase in the table temperature.
