Did you know? Here’s a space weather and radio propagation educational tidbit – from http://SunSpotWatch.com – at 14:00 UTC on 2017-07-30:

The ionosphere is strongly dependent on the condition of the geomagnetic field. Earth’s geomagnetic field wraps around the Earth and the ionosphere. The solar wind drags the geomagnetic field and creates the Earth’s magnetosphere.

Despite its name, the magnetosphere is distinctly non-spherical. Earth’s magnetosphere provides for our protection from the Sun and from space.

The Sun-side of the magnetosphere is compressed toward the Earth. The night-side of the magnetosphere is dragged far out into space away from the Sun. The magnetosphere’s shape is kind of like that of a comet, facing the Sun.
