A Program of Support for HIPAS Campaigns During 1987

Abstract

This is a review of the work performed during the 1987 HIPAS campaigns through 30 September 1987. During 1987, two campaigns were undertaken, one in June and one in October, to establish the level of Very Low Frequency modulation which could be accomplished using the HIPAS radar facility to heat the polar ionosphere. During the June campaign, it was established that there was sufficient current flowing in the ionosphere to enable the heater to produce detectable modulation at almost every interval. Further, using measurements of the polarization of the VLF return on could infer the direction of the current being modulated. Data was fortuitously taken during the passage of a westward travelling surge associated with a substorm onset in the College (Alaska) area. The analysis of this event is included in this report.
