The estimate is based on data from the Large Angle and Spectrometric Coronagraph on the Solar and Heliospheric Observatory mission. On February 6, a filament eruption was spotted on the Sun south of the disc center, according to the Center of Excellence in Space Sciences.

According to analysts, Earth will be blasted by a new solar explosion on Wednesday and Thursday, which might cause a geomagnetic storm. This occurs only a week after a moderate geomagnetic storm was caused by the Sun’s tremendous outbursts hurtling toward the Earth. On February 6, a filament eruption was spotted on the Sun south of the disc center, according to tweets from the Indian Institute of Science Education and Research’s Center of Excellence in Space Sciences (CESS). The Large Angle and Spectrometric Coronagraph (LASCO) on the Solar and Heliospheric Observatory (SOHO) mission captured the eruption, according to CESS.

SOHO is a cooperative Nasa-European Space Agency mission that was started in 1995 to study the Sun. It detects coronal mass ejections on a regular basis. The CESS further stated that from February 9 (05:48 UT) to February 10 (09:53 UT), the Earth will be influenced by a moderate geomagnetic storm with a speed of 451-615 kilometers per second, which corresponds to 11.18 am IST on February 9 to 3.23 pm IST on February 10. 

“The repercussions are unlikely to be life-threatening.” On Twitter, the CESS added, “Moderate geomagnetic storms are likely.” The solar storm may also cause geomagnetic activity, which could result in the appearance of the Northern Lights.

What is the definition of a geomagnetic storm?

A geomagnetic storm, according to the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center (SWPC), is a major disturbance in Earth’s magnetosphere that occurs when energy from the solar wind is transferred very efficiently into the space environment surrounding the planet. Some high-frequency radio transmissions and low-frequency navigation may be disrupted by these storms, which are generated by intense bursts of radiation known as solar flares. They also cause significant changes in Earth’s magnetosphere’s currents, plasma, and fields.

What is coronal mass ejection (CME) and how does it happen?

This is a massive plasma and magnetic field expulsion from the Sun’s corona. CMEs travel at rates ranging from less than 250 kilometers per second (km/s) to about 3000 km/s as they leave the Sun. CMEs aimed at Earth can reach our planet in as little as 15-18 hours. The arrival of slower CMEs can take several days.
