Northern Lights and solar flares

Recent increases in solar activity, including the largest solar flare in four years, lead to hopes of seeing the aurora borealis, also known as the northern lights, in the UK. The aurora borealis is a beautiful, shimmering display of light from the upper atmosphere that is commonly seen during the night at latitudes further north than the UK. In the UK itself the chances of seeing the aurora increase the further north you go - ranging from one or two displays every 10 years in the south of England to one or two displays a week in the Shetland Islands.

This solar wind has its own magnetic field, which can "drag away" the Earth's magnetic field lines, disconnecting them from our planet.

New observations by a suite of five NASA space probes has reportedly solved the mystery of the Northern Lights, attributing the cause of the natural phenomenon to powerful currents generated by giant electrical tornadoes in outer space.
The probe cluster, called Time History of Events and Macroscale Interactions during Substorms (THEMIS), indicate that these "space tornadoes" span a volume as large as Earth and produce electrical currents exceeding 100,000 amperes.
