Also Present: 
David Gerdes, Tomasz Kacprzak (first half), Ricardo Munoz (second half)
Problems: 

During the second half of the night, after exposure 277676 the Interlock turned red and everything stopped. We tried reconfiguring and the Interlock turned green again. When the observations were resumed., everything seemed OK, bu the new images were not built nor delivered.
We tried shutting down SISPI and re-starting it, but the system didn't seem to start properly and nothing else happened.
