NORTHERN LIGHTS, NO PARKA REQUIRED
Arctic skies are dimming again after a rare burst of summer auroras. From Aug. 26th to 29th, Earth passed through a region of space where the interplanetary magnetic field, IMF,



connected with our own magnetic field, opening a crack in Earth's magnetosphere. Solar wind poured in to fuel displays like this one over Anchorage, Alaska.



"The sky was full of lights," says Anthony Madden, who took the picture from Lake Hood Airport on Aug. 28th. "The best part was, it was warm enough that I did not need a parka."

The storms are subsiding now, but they could return on Sept. 2nd when Earth crosses through a fold in the heliospheric current sheet. This is called a "solar sector boundary crossing," and NOAA forecasters estimate a 70% chance of polar geomagnetic storms when it occurs.
