              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I Restarted tcc at 18:00 tonight
We had a couple more slew issues during 2nd half tonight.  We reset rot1 controller, but we still had an issue after that reset.  We only did a couple other slews after so the problem may still be present.  Emails were sent to the engineering staff with the details.
Conner had us doing some filter move tests with ARCTIC,  I left the cover off ARCTIC in case Russet wanted to do more tests during the day.  The filter was centered when I did my instrument fills this morning.
