Double CME blow could spark G3 geomagnetic storm! Solar flare causes radio blackout over Pacific Ocean
As we approach the solar maximum, which is the peak of the Sun's 11-year cycle, solar activity has been steadily increasing. Last month, Earth experienced a 20 nT jolt as a CME prematurely hit the planet. In March, we also experienced the worst solar storm in six years as a G4-class geomagnetic storm hit the planet on March 23, as Earth's "shields were down”. Forecasters have now warned that yet another double event could be on the horizon as two Coronal Mass Ejections (CMEs) have been observed being hurled towards Earth.
According to a report by spaceweather.com, NASA's Solar Dynamics Observatory (SDO) captured the eruption of sunspot AR3386 on August 5 which produced a dangerous X1.6-class solar flare, along with a CME. Its Solar and Heliospheric Observatory also observed a bright CME escaping from the blast side. Moreover, a magnetic filament also produced another CME that was hurled towards Earth on the same day.
According to NASA, if one of these CMEs hit Earth tomorrow, August 8, it could result in a minor G1-class geomagnetic storm. G1-class geomagnetic storms are considered minor storms, and they generally don't cause a lot of damage. On the other hand, if both these CMEs strike Earth, the double blow could result in a moderate G2 or strong G3-class geomagnetic storm.
The solar flare hurled out by the active sunspot AR3386 was of X 1.6 intensity. These flares can create radiation storms which have the potential to not only harm the satellites but also give small doses of radiation to the people flying in airplanes at the time! Moreover, these devastating flares can disrupt global communications and bring down the power grids to create blackouts.
A similar event occurred as this solar flare ionized the top of Earth's
