Thomas Vo, Sheila, Fil

We lost lock on our attempt to transition from ETMY ESD to the ITMX ESD, because of a mistake I made in the script.  We want to be able to lock DARM on the ITM ESD driver so that we can lock the interferometer with one of the end station ESDs grounded and still transition to low noise low voltage (it seems like we have plenty of range to do this on ITMX).  

While we were unlocked we went to the floor with Fil and grounded all 5 cables, shield and pin, from the ITM ESDs.  We were locked like this from 22:52:00 UTC until 23:01 UTC on August 10th.  We saw no difference in the spectrum compared to our normal noise.  I went to the floor and attempted to reconnect the ESD cables for ITMY, with the driver powered off.  I connected the cables for the 4 quadrants but unlocked the IFO connecting the bias cable.  At LLO they were able to disconnect and reconnect these cables while in lock.
