After the show at 01.00 hrs:
the Northern lights, Aurora Borealis.
The sun gives off high-energy charged particles (also called
ions) that travel out into space at speeds of 300 to 1200
kilometres per second. A cloud of such particles is called a
plasma. The stream of plasma coming from the sun is known as
the solar wind. |

As the solar wind interacts with the edge of the earth's
magnetic field, some of the particles are trapped by it and
they follow the lines of magnetic force down into the
ionosphere, the section of the earth's atmosphere that
extends from about 60 to 600 kilometres above the earth's
surface. When the particles collide with the gases in the
ionosphere they start to glow, producing the spectacle that
we know as the auroras, northern and southern. |
