The CUTLASS Finland HF radar has been operated in conjunction with the EISCAT Tromsù RF ionospheric heater facility to examine a ULF wave characteristic of the development of a ®eld line resonance (FLR) driven by a cavity mode caused by a magnetospheric impulse. When the heater is on, striating the ionosphere with ®eld-aligned ionospheric electron density irregularities, a large enough radar target is generated to allow post-integration over only 1 second. When combined with 15 km range gates… CONTINUE READING
