You might get a treat in the night sky starting April 14 after a significant solar flare sent a coronal mass ejection towards Earth.
A G2 geomagnetic storm watch is in effect for Earth Thursday after a significant solar flare erupted from a location on the sun’s surface previously believed to be inactive.
The flare was rated a C1-class eruption, which normally results in little to no consequences for Earth, according to NASA. But the area on the sun that produced the flare did create a full-halo coronal mass ejection (CME) that headed straight for Earth on April 11, according to Earthsky.org.
