               ------------- ACTIVITY LOG --------------
 Observing Specialist:    G.Saurage
Photometric night, mediocre seeing.
TSPEC lost slit position displaying ??? three times. During which time it would
respond to manual set.position of the wheel and would generally come back after a
nub restart (or two).
GCAM would stop without any signal (TUI reports its happy, no audio cue or error in
log) and need communications restarted. This happened twice. We were running both
gcam and dcam, with dcam in manual and guiding on gcam when this would happen.
Russet took time at switch over, ~30 mins, to collect focus images for both DIS
cameras.
DIS ion pumps running high, both sides.
