Possibilities of VLBI observation of solar spike-like events

Radiophysics and Quantum Electronics Aims and scope

Abstract

Modern theoretical and experimental investigations of energy release fragmentation in solar flares show the necessity of observations with high space and time resolution. In this paper, we analyze earlier interferometric observations of solar radio spikes and discuss the first results of the Radiophysical Research Institute of Nizhny Novgorod (NIRFI) in this field. We describe the NIRFI's receiving and analyzing equipment, which is part of the measuring complex for solarflare investigation with high space and time resolution and enables one to analyze the form of the interference signal and its amplitude spectrum with time and frequency resolutions of up to 16.7 μsec and 100 Hz, respectively. The prospects for VLBI observation of solar flares with high space resolution are discussed.
