The pre-modecleaner had some problems re-acquiring after the last laser trip.  The symptoms were that one could
see resonant flashes but the servo never really grabbed.  The pre-modecleaner high voltage signal instead of
looking like a ramp signal, looked like three parallel lines which is probably indicative of the high voltage
oscillating.  This is also an indication that the beam is not well centred on the locking photodiode.

    I re-aligned the beam both into the pre-modecleaner and onto the locking photodiode.  Unlocked the DC output
was ~1V.  Locked, ~0.26V.  Crudely that's a visibility of 74% with the ISS off.  That is consistent with the
power throughput of the pre-modecleaner as calculated from the values displayed on the MEDM screen.

    In bring the FSS back up using the autolocker, I noticed that the common gain kept going between 0, 2 and
16 dB even though the autolocker status did not indicate the gain was being ramped.  I assume this was guardian
doing its thing.

    The ISS however seems to be exhibiting signs of one of the switches being touchy because turning the loop
on/off at times seems to have no effect.  Unless, of course, the corresponding DAC channel is intermittent.
