Solar storms that plagued the Earth this week: Massive solar flare eruption, 2 CME strikes, more

This was one of the most chaotic weeks in a long time, with two separate CME strikes, and a long-duration solar flare eruption, and a menacing sunspot facing the Earth.

The week began with a minor solar storm incident on Monday, when aurora displays were seen in some high-latitude areas. The solar activity didn't stop there as another new sunspot, AR3363, that appeared to be crackling with solar flares also began moving towards Earth's view. (Pixabay)

The very next day, the unstable region on Sun began exploding. NASA's Solar Dynamics Observatory detected a massive M6-class solar flare that kept erupting for a long duration. Reportedly, it released more energy than some X-class flares. This sparked a planet-wide shortwave radio blackout. (Pixabay)

On Wednesday, the National Oceanic and Atmospheric Administration (NOAA) prediction models confirmed that a fast-moving coronal mass ejection (CME) released during the flare eruption, and it was set to deliver a glancing blow to the Earth.  (NASA)

Solar Flare
NOAA declared a 3-day warning for solar storms as it confirmed that yet another CME cloud is also headed for our planet and can impact the magnetosphere on July 22. The first CME was expected to strike on Friday, July 21. (NASA SDO)

Solar flare
On Friday, the first of two CME struck the Earth, delivering the second minor solar storm for the week. The second CME was expected to strike by July 22 and intensify the first ongoing storm. The resultant effect has been forecasted to even spark a G3-class geomagnetic storm. Now, the weekend appears to be a quiet one, as no further solar activity is expected. But with multiple new sunspots expected to come to the Earth's view over the weekend, the next week can be even more chaotic. (Pixabay)
