Hunter Davis submitted this image to EarthSky. It’s a halo around the sun – caused by ice crystals in high thin cirrus clouds in Earth’s atmosphere – visible over Earth’s South Pole on December 18, 2015.
Hunter said he got this shot around 1 a.m. That’s right. Around the time of the December solstice, when the sun is at its southernmost point in Earth’s sky – the South Pole is in daylight 24 hours a day.
He also said it was around -20 Fahrenheit (around -30 Celsius) at the time!
Thank you, Hunter.
