Three X-class solar flares have erupted on the sun in the past week. Solar flares are bursts of energy that travel at the speed of light. Flares can cause radio blackouts and sometimes interfere with or damage satellites. They can also deliver harmful radiation to passengers on aircraft passing near the poles. NASA and NOAA forecasters are anticipating about 115 sunspots per month.
A pair of researchers predict twice as many at “solar maximum”. Over the past week, three X-class flares have spurted off from two eruptive sunspot groups. It’s a stark change from 2019, when 77 percent of the year showed no blemish anywhere.
