A strange incident occurred in the early hours of yesterday, March 13. The NASA Solar and Heliospheric Observatory (SOHO) detected that after a huge explosion, a powerful wave of coronal mass ejection (CME) escaped from the surface of the Sun. This event should not have concerned the Earth under normal circumstances since the event took place on the farside of the Sun (the side of the Sun opposite to the Earth). However, the CME blast was deemed extremely rare as it was traveling at a mind-numbing speed of 3000 kilometers per second. The shock waves from the event pushed some of the CME particles towards the Earth as well and caused a solar storm. Check details.
The event was reported by SpaceWeather.com which reported on its website, “Something big just happened on the farside of the sun. During the early hours of March 13th, SOHO coronagraphs recorded a farside halo CME apparently leaving the sun faster than 3000 km/s…Although the CME is not Earth-directed, it has nevertheless touched our planet…Earth's magnetic field is funneling the particles toward the poles where a type of radio blackout is underway--a polar cap absorption (PCA) event”.
In order to understand just how strange this event was, it should be known that a CME cloud moving that fast only occurs about once a decade. We come across many farside CME blasts, with one taking place as soon as last week, but these never affect the planet due to being shot in the opposite direction.
However, traveling at such a high speed, these CME clouds created a shock wave, which resulted in some particles being thrown towards the Earth. These particles have accumulated towards the polar regions and a radio blackout-like condition was seen there.
