The FSS started to oscillate this afternoon, preventing us from relocking the IMC for people to take beam profile measurements in HAM6.  We reduced the FSS common gain from 24.5 dB to -1.2dB which has reduced but not fixed the oscillation.  The IMC is now locking, but we clearly still have a large oscialltion, so it would be good to check on the gain of this loop.
