| Zusammenfassung |
| The results of analysis of helio-geophisical conditions of experiments 2007-2010 on
local modification of ionosphere by powerful HF radio waves of SURA facility
are presented. All experiment were conducted at sector of local time of Harang
discontinuity for most probable influence of powerful HF pumping during the heater
functioning on activation of natural processes at subauroral ionosphere - magnetosphere
region.
The peculiarity of these experiments was that all of these were executed with use of
operative frequency, which was higher than upper hybrid frequency for background
plasma of F2-layer maximum. It was obtained that, at least, in two experiments the
observed substorm activity in zone northern SURA heater could be stimulated by its
functionment.
It is shown that results of groundbased, International Space Station and satellite
DEMETER measurements as in vicinity a SURA location and in magnetic conjugated region
support the conclusion (output) about reasons and possibility of substorm localization by
action of SURA heater. The possible mechanisms of the local substorm activation are
discussed. |
