oai:ri.kharkov.ua:article-11242013-07-14T21:01:53Z Observations of the Type U Burst in within 10–70 МHz with the GURT Radio Telescope Наблюдения Солнечного U-всплеска в полосе частот 10–70 МГц с использованием радиотелескопа ГУРТ Dorovskyy, V. V. Konovalenko, O. O. Falkovich, I. S. Bubnov, I. N. Gridin, A. A. Shevchuk, N. V. Koval, A. A. Rutkevych, B. P. Reznik, I. I. Rucker, H. O. Panchenko, M. Belov, A. S. Khristenko, A. D. Kvasov, G. V. Yerin, S. N. Melnik, V. M. The results of the first observations of solar sporadic radio emission within 10-70 MHz with the Giant Ukrainian Radio Telescope (GURT), now under construction, are presented. Observations in such a wide range of frequencies allowed considerable increase of the probability of harmonic pairs recording, where a harmonic pair means the pair of bursts generated at the fundamental and second harmonics of the electron plasma frequency.The solar U-burst observed on 8 August, 2012 is analyzed. It was recorded at the fundamental (25 MHz) and second (50 MHz) harmonics of plasma frequency. The burst’s key features have been determined. Among these, the time delay between the fundamental and harmonic emissions was of especial interest. The fundamental emission delayed for 7.5 s with respect to the harmonic. The model of occurrence of such a delay is proposed, in which the emission source is located inside the magnetic loop containing the plasma of increased density. In this case, the delay appears due to the difference in group velocities of electromagnetic waves at fundamental and harmonic frequencies. Приведены результаты первых наблюдений спорадического радиоизлучения Солнца в полосе частот 10-70 МГц с помощью создаваемого в настоящее время Гигантского украинского радиотелескопа ГУРТ. Наблюдения в такой широкой полосе частот значительно повысило вероятность регистрации гармонических пар всплесков, т. е. всплесков, генерируемых на первой и второй гармониках электронной плазменной частоты.Анализируется солнечный U-всплеск, зарегистрированный 8 августа 2012 г., который наблюдался в излучении основной (25 МГц) и второй (50 МГц) гармоник плазменной частоты. Определены основные параметры всплеска, среди которых наибольший интерес представляет задержка прихода второй гармоники относительно первой, которая составила 7.5 с. Предложена модель формирования такой задержки, в которой источник всплеска находится внутри магнитной арки с повышенной плотностью плазмы. В таком случае задержка формируется при распространении поперечной волны внутри арки за счет разницы в групповых скоростях волн, соответствующих первой и второй гармоникам.
