Reindeer and auroras: amazing photo from Lapland

Despite the fact that two coronal mass ejections (CME) missed our planet, auroras lit up the sky over the Finnish Lapland. «I finally realized my dream of photographing reindeer with auroras overhead,» said Rayann Elzein from the municipality of Inari in the Finnish Lapland.

What sparked the auroras? A small crack formed in the Earth’s magnetic field and solar wind poured in. More auroras are expected in the near future: a hole in the Sun’s atmosphere is turning toward Earth, and it is spewing a stream of solar wind in our direction. The stream is expected to arrive on Friday, March 15. G1-class geomagnetic storms are possible on that day.
The glow of the upper atmosphere is caused by the excitation of atoms and molecules of its gases under the influence of charged particles of the solar wind.
