In the early hours of February 4, the NASA Solar Dynamics Observatory (SDO) detected a massive explosion on the far side of the Sun. It was reported that the explosion was in fact a solar flare eruption that took place inside of a huge sunspot. Back then, it was considered a lucky escape because if that explosion was directed towards the Earth, it could have resulted in a powerful solar storm event. However, now the same sunspot is facing the Earth and some astronomers fear that another explosion on the sunspot is possible, which can directly hit our planet.
The development was reported by SpaceWeather.com which mentioned on its website, “A new and potentially large sunspot is emerging over the sun's northeastern limb, right here. This is probably the same sunspot that hurled a giant plume of hot plasma into space from the farside of the Sun on Saturday”. The report also mentioned that the chances of a geoeffective flare eruption in the coming days has also boosted with the presence of this sunspot.
It is not that all sunspot explosions are dangerous. Usually, it depends on the size of the sunspot and the amount of magnetic charge contained within itself. In this case, however, this particular eruption released a lot of coronal mass ejection particles. It is a sign that the eruption was so large, the mass on the surface of the Sun was sprayed in space. If this explosion took place when the sunspot faced the Earth, there was a possibility that it could have led to a G5-class solar storm.
A solar storm that strong can damage satellites, impact mobile networks and internet connectivity as well as cause power grid failure. Although, healthwise, humans will not be directly impacted by the radiation, the disruptions to emergency
