A full moon is doing just as good a job as the sun in lighting up the sky.  Here the moon, surrounded by a clear halo, is shown hiding behind one of the frosty towers of the ICL.  A large snow drift looms in the foreground.  The week’s highlights included maintenance tasks, brief power outages, the start of a pool tournament (double elimination bracket hung on the wall), and a science fair—fun with liquid nitrogen and oobleck, a non-Newtonian fluid (which behaves in strange ways).  Although it’s still winter, the horizon in the direction of the sun is becoming noticeably brighter as summertime nears.
