              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I took an Echelle IOL at the start of the night but between the blue and comp the lamp did not turn off and the mirror did not move, causing an error that I did not notice.  I took an IOL at midnight and the end of the night.
restarted Hub and TCC
reset axis controllers (alt,az, na2, Agile)
Leveled NA2 rotator -0.170
Russet worked on the majority of on sky engineering while I worked on ARCSAT engineering tasks.
We got a bulk of the tasks finished tonight.  I think only throughput is left on the list.  Russet sent out a separate 3.5m Engineering night log and I sent out a ARCSAT Engineering night log as well.
