Geomagnetic storm likely hits Earth as tsunami blasts off Sun on Saturday

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

Center of Excellence in Space Science under Indian Institute of Science Education and Research Kolkata notified about large trans-equatorial coronal hole observed on Sun, which is spewing high-speed solar wind and likely to interact with Earth is magnetosphere

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

“Solar active regions AR13056 and AR13057 have been marked as flare producer,” the agency, which observes the Sun, said in a tweet.

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

The shockwave suggested a Type-II solar radio burst that a CME was ripping through the Sun’s atmosphere at 38,26,800 kilometers per hour.

Forecasters from the National Oceanic and Atmospheric Administration have issued an alert saying there is little chance of a G1- to G2-class (moderate to moderate) storm progressing to a category G3 (strong).

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