              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Partly cloudy all 1st half, complicating some of the engineering tasks. Wind and
humidity increasing 2nd half, temps dropped suddenly making poor seeing terrible,
and focusing difficult.
ENG tasks:
-tcam mask check (Joe)
-ecam mask check, ND filter characterization (Joe)
-NA1 pointing correction
-SPIcam inst block
-Collimation: 1st tried with SH but seeing was too poor to collect productive data.
Then tried collimaion check with SPIcam. Seeing was still a problem but Russet
thinks it looks ok. Try the SH collimation tomorrow if seeing is better.
-Pointing model: Struggled to get anything at all with 3" seeing. TPOINT says it
"Could not open data file" for tonight's file, so it was not analyzed or
implemented. It was not very successful in finding many stars due to the poor
seeing.
