              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Russet did most of the work for the engineering
DIS Blue focus adjustment
DIS slit vs. instrument focus
Instrument block for imager and both cameras
New slitmasks created for 1.5, 0.9, and 2.0 slits
I updated the boresight to better match the above 3 slits (It was slightly too high)
DIS Throughput: PG1708, BD28, G191B2B
No problems
2nd half observers wanted to take dome flats with ARCTIC at the end of the night, so instrument was left mounted.
