Ja-voule'..I was thinking the same thing [link to www.swpc.noaa.gov] where has that come from,anyone!?

Preeceding the Proton Alert Onset we had a Type 2 Radio Emmission and then type 4 Radio Emmision,the latter usually indicates that there has been a particularly Violent Eruption on the Sun and often indicate a strong CME and/or Solar Radiation Storms.
