Abstract : Using a series of high latitude stations ranging from Thule, Greenland to Westford, MA, it was possible to plot the development of those irregularities affecting GPS propagation during magnetic storms. In this report we show the dynamics of the storm of November 1993 as it moves from auroral latitudes to sub-auroral regions. The same storm had an impact in the equatorial region creating irregularities at the equator and at latitudes about 18 degrees from the equator (Santiago, Chile). Other storms are being studied in order to understand the necessary conditions for development of irregularities at high and equatorial latitudes.
