              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I confirmed that the teritary clamps were engaged at NA2, where it was left this morning before I moved the tertiary this afternoon.  I then rotated the tertiary to NA1 and again confirmed that the clamps were engaged there as well, ie. '0 0 0 1' status.
I changed to NA2 port for 2nd half.  I checked the clamp status after the rotation and it reported clamped.
No problems tonight with the tertiary mirror and telescope pointing was very good as well.
