Fig. 1

Computed geoelectric field distribution on November 24, 2001 at 07:32 UT. The colored circles show the three station groups used in spatial averaging: blue, green, and red groups. The green group generates the largest average geoelectric field magnitude of 2.8 V/km. Note that the maximum geoelectric field amplitude indicated in the top of the figure refers to a single station maximum, not to group average. Corrected geomagnetic coordinates and Oblique Mercator map projection are used
