Auroras are dancing around the poles in response to a high-speed solar wind stream buffeting Earth’s magnetic field. Stefan Christmann sends this picture from icy Atka Bay in Antarctica.
“On July 1st we enjoyed a beautiful display of aurora australis over the German Antarctic Research Station Neumayer III” says Stefan. “The air temperature was -30°C with 10 knots of wind. Even so, this was one of the most beautiful expierences so far.”
NOAA forecasters estimate a 35% chance of continued geomagnetic activity as the solar wind continues to blow.
