              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland

Note from Cary: Please change arcsat filters tomorrow. Cary will not be in due to jury duty.
Speaking of arcsat, see PR2278.

NM06 took NM02's scheduled time for A-half.

Some questionable looking clouds kept us closed at the start of the night. But around 19:20 they cleared up and we had nice clear skies. 

Restarted dataq around 3:15am.

We did eyepiece for a little while tonight and got some really cool views of Jupiter, Whirlpool Galaxy, and Orion's nebula :D Space is really cool.
