The National Oceanic and Atmospheric Administration (NOAA) and other space organisations pushed away the news of any huge geomagnetic storm hitting the Earth, but said that instead of it, there would be the colourful Northern lights giving a treat for the eyes.

The massive magnetic storm was said to hit Earth on March 18, but now several scientific organisations deny the fact. The storm, which is also known as solar storm, was a temporary disturbance caused by solar wind shock wave in the Earth’s magnetosphere.

It was said that the storm will affect the telecommunication systems, thus upsetting the radio communications and will cause radar blackouts and disrupt radio navigating system.

The Space Weather Prediction Centre predicted that there will be a G1 category storm, which is a minor in all levels, on March 14 and March 15 night, which will give rise to the Aurora Borealis, commonly known as the Northern Lights, in North America and Canada.

According to reports, when the minor magnetic storm will pass through the Earth’s magnetic field, it will cause very minor disturbances in the speed of the solar winds, thus giving rise to the Co-Rotating Interaction Region (CIR) and Coronal Hole High-Speed Stream (CH HSS), which will collectively increase the display limit of the Aurora Borealis in the northern region.

The CIR will make the solar winds spiral away from the Sun, which will lead to faster-moving stream of orange and red auroras pile up on the slower part of the greens and blues. This will make a ribbon of solar particles between both the colour regions, which will have strong magnetic fields embedded in it. These magnetic fields when interacted with the Earth’s magnetosphere can produce a shock which can ramp up the geomagnetic activity.

The faster regions of the flow will be CH HSS, which are caused by openings in the solar corona or the atmosphere of the Sun. These openings are named the coronal holes.
