The sun back-lights the South Pole Telescope (SPT) on March 20th; just a couple more days until it is gone for 6 months
The sun finally set for six months on
about March 22. It is hard to pinpoint the day and time of sunset
because the sun sets very slowly and the refractive index of the
atmosphere is variable. The sun just appears to rotate 360
degrees around us as it slowly sets. We had a sunset dinner on
Saturday, the 23rd, and it was a beautiful sight to watch the last
glow of the sun sink away, not to be seen again until about
Spetember 23rd. south pole telescope south pole telescope sunset cloud striations near sunset

The
flagline to the Dark Sector is ready for the upcoming 6 months without
the sun. SPT is just visible in the distance at the end of the flagline.
