Solar radiation storm and shock wave sends CME towards Earth

November 26, 2011 – RADIATION STORM: A minor radiation storm is in progress. The protons making up this storm were accelerated toward Earth by shock waves in a CME that left the sun around 0700 UT on Nov. 26th. This event could have an effect on high-latitude HF radio communication. A solar wind flowing from the southern coronal hole (above) could reach Earth as early as Nov. 29. Solar wind speed is currently 364 km/sec with a proton density reading of 4.3 protons/cm3 –Space Watch
