Notes from my time at the South Pole, where I am working on the Keck Array, a collection of microwave telescopes that measure the polarization of the Cosmic Microwave Background.

Winter Solstice
The winter solstice was Dec 22nd down here. I used the south pole to measure the angle of inclination of earth's axis. I got 24.5 degrees, the real number is 23.5 degrees.
