Yesterday, it was reported that a ring-shaped sunspot group grew 10-folds in just a period of 24 hours and was posing a threat of solar flare eruption for the Earth. But that is a problem for the future. The immediate concern is a giant cloud of coronal mass ejection (CME) which is fast approaching our planet. The National Oceanic and Atmospheric Administration (NOAA) has revealed that there is a possibility that it can deliver glancing blows to the Earth and cause a solar storm event today, April 5. Know its possible consequences.
The development was reported by SpaceWeather.com which noted in its website, “NOAA forecasters say that a CME might pass close to Earth today. It is debris from a magnetic filament that erupted from the sun on March 30th. A glancing blow could spark minor geomagnetic storms and Arctic auroras”.
This CME was released from the Sun on March 30, when a massive magnetic filament was seen by NASA telescopes. As CME moves slower than solar winds, it took the solar particles almost a week to reach the Earth. Luckily, the current forecast suggests that we will only get glancing blows from the cloud. This means that the resultant geomagnetic storm will not be a major one and will be restricted to G1-class or a G2-class storm.
However, there is more bad news brewing for the days to come. Another new sunspot, named AR3270, has been detected by the NASA Solar Dynamics Observatory. The sunspot has two primary dark cores, both larger than the Earth. The sunspot is carrying an unstable delta-class magnetic field and can explode in the days to come. Our planet can face radio blackouts and GPS disruptions, as well as another bout of geomagnetic storm.
