The sun has had major solar flares on its surface this week that have affected communications on Earth and according to the National Oceanic and Atmospheric Administration (NOAA), those flares could send a shockwave through Earth today. Solar flares are bursts of radiation on the sun’s surface. NASA says the disturbance to Earth’s atmosphere can disrupt GPS and communications signals.

 

These “solar events” caused brief blackouts in high frequency communications when they struck, twice on Tuesday morning and once Wednesday, all between the hours of 7am and 9am ET.  

 

NOAA reports that one of the flares created a “coronal mass ejection” that actually could come into contact with Earth today. The ejection is essentially a huge cloud of plasma that could hit the Earth and cause a shock wave, affecting communications systems. If an ejection were to hit Earth today,  scientists expect it would only cause a minor geo-magnetic storm.  The flares were observed by NASA, which posted stunning photos and videos of the events on its website.
