✦ Synopsis

Electromagnetic data recorded in conjunction with the Sprites |84 campaign are presented[ The primary data set consists of electric and magnetic _eld waveforms related to visually identi_ed sprites and elves recorded on the night of 13Ð14 July 0884[ The data were collected near State College\ PA\ from a mesoscale convective system "MCS# located about 1099 km away near Lubbock\ TX[ The optical events were visually identi_ed from an observation station in Fort Collins\ CO[ Presented are the waveforms of the sferics\ a description of the measurement system\ and a discussion of the signature traits of optical event!producing sferics[ All of the sferics recorded which were related to visually identi_ed events exhibited primarily unipolar {slow tail| electromagnetic signatures of order one millisecond duration in the direction indicating positive lightning[ Similar waveforms of opposite polarity\ indicating ordinary negative lightning\ were not accompanied by any observed high altitude optical events[ Þ 0887 Elsevier Science Ltd[ All rights reserved[
