Trans-Atlantic Geopotentials During the July 2000 Solar Event and Geomagnetic Storm

The large solar activity in mid-July 2000 produced a severe geomagnetic storm at Earth during the last half of 15 July universal time. The enhancements and changes in the ionosphere electrical current systems caused large geopotentials to be induced over oceanic distances. Across the northern Atlant...

Description
Summary:The large solar activity in mid-July 2000 produced a severe geomagnetic storm at Earth during the last half of 15 July universal time. The enhancements and changes in the ionosphere electrical current systems caused large geopotentials to be induced over oceanic distances. Across the northern Atlantic, from New Jersey to near the French coast, a geopotential as large as 0.05 V km^sup -1^ (a peak-to-peak voltage of about 300 V) was measured during the geomagnetic storm. While large, this was not among the four largest such geopotentials that have been recorded in the last 60 years across AT&T telecommunications cable routes, ocean and continental. The geomagnetic and geopotential data that were measured during the storm event are presented and discussed.[PUBLICATION ABSTRACT]
