                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
Engineering Task List
Clear night tasks
-----------------
1) Zero Rotator - Completed 0.230 deg change
2) Epsilon Aur (evenings when telescope is cooling, Echelle one
night TSpec another) - Completed both TSPEC and Echelle
3) PTG Model - Completed and implemented new model
Clouds rolled in during the last portion of the pointing model.  Russet and I felt that the
collimation really needed better conditions (clouds can interfere with the data collection) and
the NICFPS bright star test also needed better skies too.  Fastcam was left and it tend to like
fainter stars and clouds too can play havoc with data collection, so I waited for the conditions
to improve some.  I did the Br. Qrtz Linearity Tests with Agile to finish the night.
4) Collimation check
5) Fastcam (per wiki,note new wind rules)
6) Out of focus Nicfps bright star tests for JW. (email instructions
to be sent next)
Cloudy night tasks
------------------
1) Br. Qrtz Linearity Tests (Agile) - Finished
2) Dim Qrtz Linearity Tests (Agile)
