Earth is under a solar storm warning for Wednesday due to the chance of a minor G1-class geomagnetic storm hitting our planet.
High-speed solar winds from a “hole” in the sun’s atmosphere are set to hit Earth’s magnetic field on Wednesday. This will trigger a minor G-1 geomagnetic storm.
Although it might be a minor storm, scientists warned that it might have a slight impact on Earth’s geomagnetic field and cause radio and GPS signal disruptions.
The National Oceanic and Atmospheric Administration (NOAA) classifies geometric storms in five stages – one being the weakest and five the strongest.
And the one set for Wednesday will have a very low impact on satellites and technologies on Earth.
However, it may confuse migratory animals that use Earth’s magnetic field as a navigational tool.
The Earth’s magnetosphere is created by our magnetic field and protects us from most of the particles the sun emits. When a CME or high-speed stream arrives at Earth it buffets the magnetosphere. If the arriving solar magnetic field is directed southward, it interacts strongly with the oppositely oriented magnetic field of the Earth.
The Earth’s magnetic field is then peeled open like an onion allowing energetic solar wind particles to stream down the field lines to hit the atmosphere over the poles. At the Earth’s surface a magnetic storm is seen as a rapid drop in the Earth’s magnetic field strength. This decrease lasts about 6 to 12 hours, after which the magnetic field gradually recovers over a period of several days.
