Alberto Alvarez
Also Present:

Problems: 

1) Telescope brake engaged at beginning of night. Resolved by crew cleaning the encoders. Lost the first half hour of the night to this.

 2) Windscreen, in raised position, failed to respond. Resolved by replacing fuses (at least two different fuses). Lost no time to this. 

Comments: 

See above.

Was RASICAM flat field updated? It looks a lot better, although date of current display is wrong (off by ~32 hours).
