A series of solar active regions unleashed an extraordinary display of solar activity in October and November of 2003. You can view the affects in the near-Space Weather Prediction in plots of the GOES Space Weather Prediction Monitor data (October, November, PDF, ~.5 MB each). These plots show the series of significant flare events from October 19th through November 5th which included 17 flares of class M5 or above, 11 of these were X-class flares. The X28 flare on November 4th is the largest ever recorded. http://sxi.ngdc.noaa.gov/sxi_greatest...
