  Hi Jean-Pierre, Alan, my friends,

At this moment (yesterday december 13th, about 0300 UT) it was only, photons (UV, X, perhaps gamma), with no weight, and so travelling at the speed of light. The speed of the large particles (electrons, protons and heavier ions as atoms nuclei), is more difficult to foresee, 1000, 2000 km/s, more or less... They need hours to travel. Maybe they only are reaching the earth now, but more likely it was yesterday, but sometime about 30 hours after they left the sun, with the usual effects on the earth magnetic field, auroras, and LF conditions (?).
  Best 73 !

  Jean-Pierre (another one, f5yg)
