              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Echelle IOL taken for Bill
Clouds during the afternoon, but partial clearing at sunset allowed us to open on time.
Clouds started coming in again around 21:30
First light with ARCTIC!!!  We see stars!!!
A focus sweep, then a couple "first light" pictures then the clouds stopped us as we were ready to start the instrument block.
We re-opened around 01:40.
