Incoming Space Weather: CME/Coronal Hole (April 18th-20th, 2011)

M-FLARE: The magnetic canopy of sunspot 1190 erupted on April 15th, producing an M-class solar flare. The brief blast did not, however, hurl a cloud of plasma toward Earth. NOAA forecasters estimate a 55% chance of more M-flares during the next 24 hours.
