I think that that map is of where the EM (electromagnetic radiation) hit the Earth a few minutes after the solar flare erupted (traveling at the speed of light). Data suggests that the flare also produced a nice CME (coronal mass ejection -- of mostly electrons and protons). They estimate that the bulk of those particles are moving at slightly over 2 million miles per hour, so about 40 hours or so from Earth. The Earth will have moved a bit in its orbit since the CME, so those particles won't make a direct hit like the EM, but they will cause a nice geomagnetic storm. If the conditions are right, Asia should be the first to see the auroras starting about 15:00 UTC (Coordinated Universal TIme), with the show moving westward on the opposite side of the Earth from the Sun.
