For the next few days, Earth is expected to skim through a number of minor solar wind streams
associated with a southern hole in the sun’s atmosphere.
This will likely stir magnetic unrest around Earth’s poles, albeit not full-fledged geomagnetic storms. Intermittent Arctic auroras are possible this weekend.
Solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma consists of mostly electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV.
Embedded within the solar-wind plasma is the interplanetary magnetic field. The solar wind varies in density, temperature and speed over time and over solar latitude and longitude.
Its particles can escape the Sun’s gravity because of their high energy resulting from the high temperature of the corona, which in turn is a result of the coronal magnetic field.
This will cause beautiful Arctic auroras to continue for the next few days.
Additionally minor disturbances in low frequency radio waves and minor interference of low orbit satellites.
Although our sun has entered recently a Solar Minimum, meaning the sun goes into its ‘quiet phase’ we are still seeing quite a lot of activity from our sun associated with coronal holes.
Some researchers claim that geomagnetic storms and solar streams can cause earthquakes and volcanic activity to increase when the blast of particles hits our earth.
