                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds and rain nearby kept us closed for a few hours after sunset,
 then we were able to open with a careful eye on conditions.  Several
 waves of thin clouds passed through and we closed briefly for a
 humidity spike.  Seeing was good (but not quite stable) with
 NIC-FPS, poor with APOLLO at rather high airmass.
 When I tried to focus the guider, the gmech piston was far out of
 position and in trying to correct that I managed to render the gmech
 completely incommunicado.  This wasn't critical since guiding wasn't
 needed with NIC-FPS, but I had hoped to run the autofocus script.
 During the move to APOLLO, the tertiary failed with a CHKMV error
 indicating that it had fallen too far behind its target position.
 After I homed the mirror it behaved well; only a couple of minutes
 of time were lost.
