              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Heavy clouds and some rain at the start of the night.  Ran an in-dome
pointing model starting at 18:30.
Echelle interorder light was measured at 13.9.
At 21:20 restarted DIS linearity test, completed around 02:20.
Echelle spectral jump was investigated by R.McMillan.
At 02:40 began DIS repeatability test, DIS seems consistent.
Weather did not allow for any on-sky observations/engineering.
