The HF ionospheric modification (heating) facility at Ramfjordmoen will become a part of the
EISCAT association from January 1993. This paper, which is intended for the new user …

Active ionospheric experiments using high-power, high-frequency transmitters,“heaters”, to
study plasma processes in the ionosphere and magnetosphere continue to provide new …

Twenty‐two theoretical mechanisms for auroral arcs are examined (12 electron‐acceleration
mechanisms and 10 generator mechanisms) and a characteristic auroral‐arc thickness is …

The high‐power HF (high‐frequency) facility (commonly known as Heating) near Tromsø,
Norway, which is an essential part of the European Incoherent Scatter Scientific Association …

New EISCAT observations of large field‐aligned bulk ion outflows from the topside
ionosphere during auroral activity are presented. The ions (mainly O+) start their outflows …

Broadband electric field fluctuations with typical amplitudes of 10–20 mV/m peak‐to‐peak
and frequencies from 0 Hz to 3 kHz (BB‐ELF) were observed coincident with a region of≤ …

We have investigated how geomagnetic activity, the solar wind (SW), and the interplanetary
magnetic field (IMF) influence the occurrence of the F‐region/topside ionospheric ion upflow …

The widespread existence of naturally excited broadband electrostatic wave activity up to 15
kHz, with predominantly parallel polarization, have been detected in the topside auroral …
