According to Newsweek, Lebedev Institute and NOAA have similar forecasts for March 18's geomagnetic activity, as the institutions are both expecting a "minor" magnetic storm on that day as the worst case scenario.

The incoming solar storm has seen an enormous explosion on the surface of the Sun that has blasted an array of solar particles towards the Earth.

Even though a G1 minor geomagnetic storm on March 18 is nothing to worry about, on the other hand, a massive storm, such as one originally reported yesterday, could carry unsafe consequences.

Northern Lights can be an effect of a geomagnetic solar storm.

"The storm is impressive by recent standards, but nowhere near the maximum intensities often generated at the height of the solar cycle".

When the clouds react with the Earth, they can interact with the Earth's magnetic field and cause geomagnetic storms.

Usually, geomagnetic storms are cataloged in 5 different main levels depending on the magnitude, from G1 to G5 levels of geomagnetic storms' magnitudes. Meteorologists are predicting a G1-level storm - the lowest level on the solar storm scale, which peaks at G5. This basically means there could be some slight glitches to satellite communications and power grid controllers. Still, the Space Weather Prediction Center in Boulder, Colorado says the famous Northern Lights could be seen across Canada and the northernmost parts of the USA such as ME and MI. As per the stats, Earth faces over 2,000 G1 categories' geomagnetic storms in every 11 years i.e. about twice a day. The most extreme storms can impact satellites and disrupt power grids on Earth. One storm occurred in 1859, while the latter occurred in 1989, which resulted in a nine-hour blackout in Canada. Note that there are certain beliefs associated with solar storms that aren't proved yet as per which, these storms can cause headaches, sleeplessness, and dizziness too.

The Northern Lights is a natural display in the earth's sky, which are predominantly normally seen in high-latitude regions such as around the Arctic and Antarctic.
