Geomagnetic storm likely hits Earth as tsunami blasts sun Saturday


A geomagnetic storm is likely to begin around Earth as a full halo explosion from the Sun hits the planet on Saturday. A coronal mass ejection (CME) is expected to hit Earth’s magnetic field as storm clouds move faster than the Sun on Thursday.

The Space Science Center of Excellence at the Indian Institute of Science Education and Research, Kolkata has reported a large transequatorial coronal hole observed on the Sun, which spits out high-velocity solar wind and is likely to interact with the Earth in the magnetosphere

Coronal mass ejections often occur right after a star shines or a sudden, bright burst of radiation can travel far into space. A coronal mass ejection is one of the largest eruptions from the surface of the Sun that can propel up to a billion tons of material into space at several million kilometers per hour. This solar material exits through the interplanetary medium, affecting any planet or spacecraft in its path.

“Active solar regions AR13056 and AR13057 have been marked as flare producers,” the Sun-observing agency said in a tweet.

Meanwhile, according to, sunspot AR3060 erupted in the early hours of July 21, causing a C5-class solar flare and solar tsunami. The eruption was observed by NASA’s Solar Dynamics Observatory, which reversed shock waves seen in the extreme ultraviolet.

The shock wave suggested a type II solar radio burst indicating that a CME was tearing through the Sun’s atmosphere at 38,26,800 kilometers per hour.

Forecasters from the National Oceanic and Atmospheric Administration have issued an alert that a G1 to G2 (moderate to moderate) class storm is unlikely to progress to a G3 (strong) category.

A geomagnetic storm is a major disturbance of the Earth’s magnetosphere that occurs when there is a very efficient exchange of energy between the solar wind and the surrounding space environment of the Earth.
