Abstract

TEC maps show the intensification and spread of the 11 May 2024 extreme auroral event across the continental US over a 20-minute interval. All sky camera imagery indicates that the TEC enhancement closely matches the westward and equatorward expansion of strong red aurora. Coincident with auroral breakup, individual receiver/satellite data sets show sharp bursts of greatly elevated TEC 50 TECu above background.
