Fun with cryogen

Well, I escaped the usual daily activities by helping our Cryogenics Tech Chris do a liquid nitrogen fill for one of the telescopes over in the Dark Sector. We collected the four dewars from the Dark Sector Lab (insulated flasks in which cryogens are stored and transported), hoisted them down from the second floor, and took them over to MAPO on a snow mobile sled to where the N2 plant is located. We filled the dewars up with more liquid nitrogen, and then returned them all to DSL so the telescope grantee could use it to cool his instrument. It was a nice change of scene and pace.

In the evening I joined some friends out in ARO to watch the truly atrocious movie "Ladyhawke". We blocked off all the windows to shut out the omnipresent sunshine, and had a nice relaxing time despite the movie's shortcomings.
