SHINE_2006 The bulk of the 3 x g of material reached 1 AU in about one day indicating an average speed for this mass of approximately 1600 km s -1, or a total kinetic energy for the CME of ~2 x ergs. 20 January 2005 CME

A similar efficiency has been estimated for cosmic ray acceleration by supernova shocks. (Mostly from Dick Mewaldt – SHINE 2005) | ∆ - 1/20/05 | 20 January 2005 CME
