A new solar cycle has begun and already it has produced its first light--an outbreak of auroras on Jan. 5th. "It was a nice flowing display that persisted for an hour and a half," reports photographer Calvin Hall of Palmer, Alaska. "A Great Horned Owl would hoot when the auroras were most active."
The lights were sparked by a solar wind stream that hit Earth late on Jan. 4th. Our planet is still inside the stream, which means more auroras are possible tonight. High-latitude sky watchers, when the owl hoots, look up!
