Monster sunspot triggers fears of solar storm strike on Earth; Can spark solar flare eruptions

After an unexpected solar storm event in the late night of September 2, that extended well into the morning of September 3, many scientists believe that such solar activities will now continue to increase till the equinox on September 23. During equinoxes, the Earth's magnetic poles (north and south) are at right angles to the solar wind. This makes the solar wind stronger, which can cause stronger magnetic storms. To increase the troubles, a new sunspot, AR3421, has also emerged directly in view of the Earth. The sunspot contains a mixed polarity magnetic field that can often create powerful solar flare eruptions. In case a large enough coronal mass ejection (CME) is released during the event, it can trigger a destructive solar storm.,

As per a report by SpaceWeather.com, “A new sunspot is emerging on the sun's central meridian, directly facing Earth. Numbered AR3421, the active region has a mixed polarity .magnetic field that could harbor energy for geoeffective flares”.

While the presence of a sunspot does not automatically guarantee solar activity, it is likely when such regions contain opposing magnetic fields, as they often trigger solar flares. Once a solar flare erupts in Earth's direction, the massive ultraviolet radiation can often cause radio blackouts on Earth, limiting short-range wireless communications.

The main challenge comes from any CME clouds that are geoeffective as they can trigger powerful solar storms. In worst-case scenarios, such solar storms can not only damage satellites and disrupt wireless communications such as internet services, mobile networks, and GPS, they can also cause power grid failures and even disrupt electronics such as heart pacemakers on Earth.
