SOLAR TSUNAMI AND CME: Earth-facing sunspot AR2816 exploded this morning, producing a C3.8-class solar flare. A pulse of X-rays and UV radiation ionized the top of Earth’s atmosphere, producing a shortwave radio blackout over southeast Asia. Of greater interest, however, is this shadowy wave rippling away from the blast site. A G2-class geomagnetic storm is possible on April 25th when a coronal mass ejection (CME) is expected to hit Earth’s magnetic field. The CME was hurled in our direction earlier today by a C3.8-class flare from sunspot AR2816. Auroras could dip into northern-tier US states from Maine to Washington
