On April 17, NASA’s Solar Dynamics Observatory (SDO) captured the blow of an X1-class solar flare caused by massive group of sunspots detected on the sun’s northeast limb the day before.

While the flare produced an x-ray pulse that caused a powerful shortwave radio blackout throughout parts of the southern hemisphere, the Coronal Mass Ejection (CME) appears to have largely overlooked the Earth on this occasion.Solar flares are classified according to their strength, with A-class being the weakest, followed by ‘B’, ‘C’, and ‘M’ Class, and X-class being the strongest.

Flares are light bursts that are sometimes associated with CMEs that release globules of charged particles into space.Nevertheless, because the sunspot group in question has been involved for more than a week, it is gradually turning to face the Earth, raising the prospect of further flare activity, and the sunspot group shows no signs of slowing down.

#spaceweather A big & very active sunspot complex emerged over sun’s northeastern limb yesterday. It has already produced an X1-class solar flare.

As a result, we can expect to see aurora borealis sightings across Wales again in the coming week and into the weekend.
