Also Present:

Problems: 

Lost ~1hr at beginning of the night waiting for a potential TCS fix.  German replaced the TCS kernel in hopes of eliminating a bothersome problem with TCS disconnects every 2h 40m.  Unfortunately didn't eliminate problem. Each time had to stop observing, go to zenith, restart systems (in particular, mirror air) and slew back to our field.  Time lost ~30min.  

 

Typically had OCS interlock failure one or two images after recovering from TCS, but a quick "Reset" resolved those.
