On Sunday (November 29), the sun released its strongest solar eruption in more than three years.

A solar flare is a sudden, bright explosion of electromagnetic energy, measured by the M4.4 used by astronomers for storms. M-class flares are medium-scale outbreaks (compared to small C-class flares and large X-class flares) with a rating ranging from 1

to 9, with larger numbers representing stronger flares.
