Reprinted from Space Weather News for Dec. 20, 2014
Solar activity is high. A pair of large sunspots is crossing the center of the solar disk, and both are crackling with flares. The strongest so far, an X1.8-class flare on Dec. 20th, caused a strong HF radio blackout over the South Pacific and might have hurled a CME toward Earth.
