              ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Photometric night, mediocre seeing.
Two issues to note:
1. During checkout test slews the NA2 rotator would not init. TUI status continued
to report buffer control empty. I logged into controller box and ultimately had to
reset. Behaved normally after that.
2. BC1 eyelid would not fully open. The inside or port eyelid opened fine but the
matching cover eyelid would not open at all. It behaved the same in auto or manual.
Slewing to high altitude and closing and re-opening the entire mirror covers seemed
to put the top petal back into the correct place. Upon opening it made a lot of
racket and then the eyelids worked properly. PR#1125
