Nasa’s Solar Dynamics Observatory observed the sun as a significant solar flare burst from its left side, peaking at 7.42 am EDT on 10 June. The sun then released a second X-class flare which peaked just over an hour later at 8.52am.
The third, classified as an X1.0, erupted today and peaked at 5:06 a.m. EDT.
Nasa explains that solar flares are the most powerful bursts of radiation that cannot pass through Earth’s atmosphere to physically affect humans on the ground.
However, the flares can disturb the Earth’s atmosphere in the layer where GPS and communications signals travel.
Tuesday’s flares, which measured X2.2 and X1.5, were reportedly powerful enough to temporarily interfere with radio communications in Europe.
Could be worse. Will be, one day.
