Pink Northern lights — amazing!

September 14, the flow of the solar wind reached the Earth's magnetic field. When its speed exceeded 600 km/s, bright pink stripe appeared over Yellowknife in Canada. Martin male has made this a mesmerizing picture, noting that the pink color had struck him.

Pink is a sign of nitrogen. Most of the Aurora green. We see the green glow when charged particles from space strike atoms of oxygen at altitudes of 100 to 300 km above the Earth's surface.

The pink color appears when the charged particles descend lower than usual, striking nitrogen molecules at an altitude of 100 km and below.The autumn equinox is the time of appearance of cracks in the Earth's magnetic field. Perhaps thanks to them, the solar wind penetrated further than usual. If so, then in the near future we will be able to admire a large number of pink ("nitrogen") of the Aurora.

To equinox less than a week away, and the Earth is approaching a new solar wind flow.
