The Earth is being constantly bombarded by solar storms this week. On February 26 and 27, two consecutive coronal mass ejection (CME) clouds struck the Earth, with the latter being recorded as a highly intense G3-class solar storm which caused auroras to be displayed as south as Colorado, delayed a SpaceX rocket launch and caused oil rigs to be stopped in Canada. And yesterday, the unstable sunspot AR3234 again exploded resulting in a M8.6 class solar flare eruption. It was detected by the NASA Solar Dynamics Observatory (SDO). This massive eruption sparked shortwave radio blackouts across the American continents and fears are that another set of solar storms can be triggered because of it.
The event was reported by SpaceWeather.com which noted on its website, “Sunspot AR3234 exploded today, Feb. 28th at 1750 UTC, producing an M8.6-class solar flare, percentage points below X-class. An impulsive burst of X-rays ionized the top of Earth's atmosphere, causing a shortwave radio blackout over the Americas”. The report also highlighted that CME storms are possible in the coming days.
The geoeffective region for this ‘almost X-class' solar flare eruption was the entirety of South America, Mexico and large parts of USA and Canada. Both the American continents came under the effect of the radiation coming from the solar explosion. The radio blackout affected independent planes and drones, small ships as well as amateur radio controllers, who all struggled to broadcast and receive communications.
This is also one of the strongest solar flare explosions seen in recent times, which highlights the increasing intensity of the Sun as it reaches close to its peak. However, the danger is not over yet.
Such eruptions also release a number of
