The most powerful solar flare of the year erupted from the sun today (April 11) sparking a temporary radio blackout on Earth, NASA officials say.
The solar flare occurred at 3:16 a.m. EDT (0716 GMT) and registered as a M6.5-class sun storm, a relatively mid-level flare on the scale of solar tempests. It coincided with an eruption of super-hot solar plasma known as a coronal mass ejection.
“This is the strongest flare seen so far in 2013,” NASA spokeswoman Karen Fox explained in a statement. “Increased numbers of flares are quite common at the moment, since the sun’s normal 11-year cycle is ramping up toward solar maximum, which is expected in late 2013.”
……………. The solar flare triggered a short-lived radio communications blackout on Earth that registered as an R2 event (on a scale of R1 to R5), according to space weather scales maintained NOAA, Fox added.
