This is the strongest proton event since 2003!

Earlier, it was stated that the current Solar Radiation Storm was the largest since May 2005, when the 10 MeV protons exceeded over 3000 PFU. This was not correct.
At the time of the earlier post, this current Storm was the biggest since January 2005, when the 10 MeV flux was 5040 pfu. After the arrival of the CME earlier today, the 10 MeV flux again increased and we were at around 6300 pfu. This is now the largest Solar Radiation Storm since October 2003. (The Halloween Storms)
