              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland,R.McMillan
We had a nice and dusty start to the night. Once the dust cleared the clouds became super thick.
Opened just before 2:30am. UW02 gave up early due to more clouds rolling in, so we started NM10 a little early.
Once the weather more or less cleared, it was a quiet night with no problems.
No morning echelle iol since cals were being taken.
Also, it was Zeus's (my new dog) first night at the observatory! He did such a good job and was such a good helper!
