If you were listening to the radio Friday morning, you might have noticed something.

Perhaps there was nothing to listen to.

A two solar flares erupted from the sun Friday, causing a radio blackout, according to

Details on that blackout are on the Space Weather Prediction Center.

The flares, just after 1 a.m. Seattle time, then again just after 8 a.m., were classified by astronomers in the “X” category — the strongest.

NASA’s Solar Dynamics Observatory reported:

Increased numbers of flares are quite common at the moment, since the sun’s normal 11-year activity cycle is currently near solar maximum conditions. Humans have tracked this solar cycle continuously since it was discovered in 1843, and it is normal for there to be many flares a day during the sun’s peak activity. The first X-class flare of the current solar cycle occurred in February 2011. The largest X-class flare in this cycle was an X6.9 on Aug. 9, 2011.
