Ground Based Support of the Space Mission Parker Performed with Ukrainian Low Frequency Radio Telescopes
Vladimir Dorovskyy, Valentin Melnik, Anatolii Brazhenko
The purpose of this work is to demonstrate the effectiveness of ground-based support for space missions, primarily PSP, using large Ukrainian decameter radio telescopes. Another go…
Observations of shock propagation through turbulent plasma in the solar corona
Eoin P. Carley, Baptiste Cecconi, Hamish A. Reid +14
Eruptive activity in the solar corona can often lead to the propagation of shock waves. In the radio domain the primary signature of such shocks are type II radio bursts, observed…
Solar Type U Burst Associated with a High Coronal Loop
V. V. Dorovskyy, V. N. Melnik, A. A. Konovalenko +2
An inverted U burst with equally developed ascending and descending branches observed by Giant Ukrainian Radio Telescope (GURT) on 18 April 2017 in meter wavelengths band is discus…
Properties of Type III and Type IIIb Bursts in the Frequency Band of 8-80 MHz during PSP Perihelion at the Beginning of April 2019
V. N. Melnik, A. I. Brazhenko, A. A. Konovalenko +4
Properties of type III and type IIIb bursts in the frequency band of 8-80 MHz observed by the radio telescopes Ukrainian Radio Interferometer of NASU-2 (URAN-2) (Poltava) and Giant…
Radio signature of a distant behind-the-limb CME on 2017 September 6
V. N. Melnik, H. O. Rucker, A. I. Brazhenko +5
We discuss properties of a Type IV burst, which was observed on 2017 September 6, as a result of the powerful flare X 9.3. At decameter wavelengths this burst was observed by the r…
First observation of the solar Type III burst decay and its interpretation
Valentin N. Melnik, Alexandr A. Konovalenko, Sergey M. Yerin +6
A decay of Type III burst into two Type III bursts was registered during solar observations by GURT and URAN-2 radio telescopes on April 18, 2017. Such phenomenon was observed for…
Comparative analysis of solar radio bursts before and during CME propagation
G. Dididze, B. M. Shergelashvili, V. N. Melnik +5
As is well known, CME propagation often results in the fragmentation of the solar atmosphere on smaller regions of density (magnetic field) enhancement (depletion). It is expected…
Properties and magnetic origins of solar S-bursts
Brendan P. Clarke, Diana E. Morosan, Peter T. Gallagher +3
Context. Solar activity is often accompanied by solar radio emission, consisting of numerous types of solar radio bursts. At low frequencies (<100 MHz) radio bursts with short dura…
Solar bursts as can be observed from the lunar farside with a single antenna at very low frequencies
A. A. Stanislavsky, A. A. Konovalenko, S. N. Yerin +10
Earth-based observations are complicated by the opacity of Earth's ionosphere at very low frequencies and strong man-made radio frequency interference. This explains long standing…
Revisiting the frequency drift rates of decameter type III solar bursts observed in July-August 2002
A. A. Stanislavsky, A. A. Konovalenko, E. P. Abranin +4
Estimating for the frequency drift rates of type III solar bursts is crucial for characterizing their source development in solar corona. According to Melnik et al. (Solar Phys. 26…
Interferometric Observations of the Quiet Sun at 20 and 25 MHz in May 2014
V. N. Melnik, V. A. Shepelev, S. Poedts +3
Results of solar observations at 20 and 25 MHz by the UTR-2 (\textit{Ukrainian T-shaped Radio telescope of the second modification}) radio telescope in the interferometric session…
Decameter Type IV Burst Associated with a behind-the-limb CME Observed on 7 November 2013
V. N. Melnik, A. I. Brazhenko, A. A. Konovalenko +5
We report on the results of observations of a type IV burst by URAN-2 (Ukrainian Radio interferometer of Academy Scienses) in the frequency range 22 - 33 MHz, which is associated w…

V. N. Melnik, H. O. Rucker, A. A. Konovalenko +5
The results of the first observations of Type IV bursts at frequencies 10-30 MHz are presented. These observations were carried out at radio telescopes UTR-2 (Kharkov, Ukraine) and…
Properties of Decameter IIIb-III Pairs
V. N. Melnik, A. I. Brazhenko, A. V. Frantsuzenko +2
A large number of Type IIIb-III pairs, in which the first component is a Type IIIb burst and the second one is a Type III burst, are often recorded during decameter Type III burst…
