              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I did a manual fill of the Echelle around 18:50 tonight.  I wasn't sure if it tried an auto-fill while I was transfering LN2 (It did it around that time on Sunday night) so I just wanted to be safe and make sure there was LN2 in the instrument.
Clear until the clouds rolled in around 03:00.  At 03:50 I opted to close the dome as we were getting no data and the clouds were getting worse.
We re-opened at 04:45 between for a sucker hole so Don could get a telluric standard.  Didn't appear to be anmy precip threat, just clouds.  We called it at 05:05 as the clouds became too thick again.
I filled NICFPS and GFP at 04:15 and topped the GFP again at 05:15 when I finally closed for the night.
