Aurora in Ring. A planet full of mystery

Aurora in Ring. A planet full of mystery

Solar winds and bursts of charged particles from the Sun have made the early days of October 2002 very favorable for these early auroras.

While enjoying the stormy space weather in Toemmeraas, Norway, Trygve Lindersen captured with a digital camera this picturesque appearance of the Northern Lights on October 6, 2002.

From this perspective, green light veils formed a seemingly suspended ring just above the trees in the foreground. But the ring of light was more than 100 kilometers above the trees, and the greenish glow had been produced by the molecular oxygen that interacted with the energy electrons, near the limit with space.
