Ultra-fast solar winds that were blasted out of the Sun are darting towards Earth and could come into contact with its geomagnetic field.
The US National Oceanic and Atmospheric Administration (NOAA) warned that the G1-class storm could cause power grid failures, disrupt satellites and disrupt the migrations of animals if this happens.
While this has the potential to cause disruption, the incoming solar storm is in the lowest ranked category in terms of its intensity, meaning it is considered a minor storm.
Solar storms are ranked from G-1 minor to G-5 extreme, but even the minor storms threaten disruption when they come into contact with satellites.
The NOAA has now warned that the geomagnetic storm is “likely” to strike today as a result of a “gaseous material flowing from a southern hole in the Sun’s atmosphere”.
These coronal holes appear as dark areas in extreme ultraviolet and X-ray images and are regions where the Sun’s plasma is cooler and less dense than that surrounding it because of the star’s magnetic field which extends into space as an open field.
That allows for the rapid streams of solar wind to pour out the Sun and may even reach the Earth if the hole is facing towards the Earth.
This is a breaking story. More to follow.
