South Pole Telescope back-lit by the setting sun which will rise again in 6 months

March is the month when the sun sets and doesn't return for 6 months marking the beginning eternal darkness and beautiful polar skies. This year the setting sun created beautiful orange skies until the day of sunset, when a storm moved in and blocked out veiw of the slowly setting sun for about a week. Near the end of the month, however, the skies cleared and the two brightest stars became visible, Sirius (Alpha Canis Majoris), the brightest star and low in elevation (~16-1/2 deg) here at Pole and Canopus (Alpha Carinae), the second brightest star (~53 deg). We also finally reached temperatures of -80 F (-62 C),  marking the beginning of the long, dark, and frigid winter.

Just before sunset and the storm which created obscure skies, I took a few photos.  telescopes of the dark sector    flagline to the dark sector      walking back from MAPO        flagline to the station      sunset over the storage berms and power plant     South Pole Telescope (SPT)     SPT close-up    elevated station backlit by the sun     frosted on arrival    long walk to station     SPT and the full moon

To celebrate the setting sun and coming of the dark winter we had a nice traditional sunset dinner.    sunset dinner
