Solstice

Just as this post appears, the planet Earth is passing the Solstice – the time when the sun is as far to the south as it can possibly get. This set of image frames is one of my favorite things to check out on the day of the solstice. This is today, December 21, as captured by the American GOES-16 weather satellite, currently sitting in a geostationary orbit over the center of this frame.

Some of the Earth’s orbital details are obvious in this clip. First of all, take a look at the south pole – much of Antarctica is illuminated 24 hours today, as you can see at the southern part of this frame. At the northern edge of the clip though, the Arctic receives very little sunlight and you can spot the shadowed line where there is no sunlight received at all. You can also look at how the sun moves across this frame and really get a feel for why it’s currently southern Hemisphere summer – watch how much more sunlight the southern hemisphere gets than the northern hemisphere.
