Weekend high-speed stream of solar wind hit the Earth's magnetic field, causing massive auroras around the Arctic circle. On the night of 6 Jan Tina Salonen from Aurora Holidays noticed the sky in Utsjoki, Finland, something extraordinary — green glow with a pink fringe.

Most of the lights are painted in green — the color of the oxygen atoms faced with energetically charged particles from outer space at an altitude of 100 to 300 km above the Earth's surface. The pink color appears when cosmic particles descend lower than usual, colliding with nitrogen molecules at the 100 km level and below.

According to unconfirmed reports, the solar minimum may cause an unusual amount of pink and even white lights. Why? Chemical and magnetic composition of the solar wind during Solar minimum may differ from other phases of the solar cycle, creating your own palette of colors.
