Twin Null-Point-Associated Major Eruptive Three-Ribbon Flares with Unusual Microwave Spectra
V. V. Grechnev, N. S. Meshalkina, A. M. Uralov +7
On 23 July 2016 after 05:00\,UTC, the first 48-antenna stage of the Siberian Radioheliograph detected two flares of M7.6 and M5.5 GOES importance that occurred within half an hour…
Multi-instrument view on solar eruptive events observed with the Siberian Radioheliograph: From detection of small jets up to development of a shock wave and CME
V. V. Grechnev, S. V. Lesovoi, A. A. Kochanov +7
The first 48-antenna stage of the Siberian Radioheliograph (SRH) started single-frequency test observations early in 2016, and since August 2016 it routinely observes the Sun at se…
Correlation plots of the Siberian radioheliograph
Sergey Lesovoi, Veronika Kobets
The Siberian Solar Radio Telescope is now being upgraded. The upgrading is aimed at providing the aperture synthesis imaging in the 4-8 GHz frequency range, instead of the single-f…
Siberian Radioheliograph: First Results
S. V. Lesovoi, A. T. Altyntsev, A. A. Kochanov +9
Regular observations of active processes in the solar atmosphere have been started using the first stage of the multiwave Siberian Radioheliograph (SRH), a T-shaped 48-antenna arra…
Sources of Quasi-Periodic Pulses in the 18 August 2012 Flare
A. Altyntsev, N. Meshalkina, H. Meszarosova +3
We analyzed spatial and spectral characteristics of quasi-periodic pulses (QPP) for the 18 August 2012 limb are, using new data from a complex of spectral and imaging instruments d…
96-antenna radioheliograph
S. V. Lesovoi, A. T. Altyntsev, E. F. Ivanov +1
Here we briefly present some design approaches for a multifrequency 96-antenna radioheliograph. The array antenna configuration, transmission lines and digital receivers are the ma…
Microwave and EUV Observations of an Erupting Filament and Associated Flare and CME
C. E. Alissandrakis, A. A. Kochanov, S. Patsourakos +3
A filament eruption was observed with the Siberian Solar Radio Telescope (SSRT) on June 23 2012, starting around 06:40 UT, beyond the West limb. The filament could be followed in S…
Thermal to Nonthermal Energy Partition at the Early Rise Phase of Solar Flares
Alexander A. Altyntsev, Gregory D. Fleishman, Sergey V. Lesovoi +1
In some flares the thermal component appears much earlier than the nonthermal component in X-ray range. Using sensitive microwave observations we revisit this finding made by Batta…
Study of flare energy release using events with numerous type III-like bursts in microwaves
N. S. Meshalkina, A. T. Altyntsev, D. A. Zhdanov +4
The analysis of narrowband drifting of type III-like structures in radio bursts dynamic spectra allows to obtain unique information about primary energy release mechanisms in solar…
The multifrequency Siberian Radioheliograph
S. V. Lesovoi, A. T. Altyntsev, E. F. Ivanov +1
The 10-antenna prototype of the multifrequency Siberian radioheliograph is described. The prototype consists of four parts: antennas with broadband front-ends, analog back-ends, di…
3D Structure of Microwave Sources from Solar Rotation Stereoscopy vs Magnetic Extrapolations
Gelu M. Nita, Gregory D. Fleishman, Ju Jing +5
We use rotation stereoscopy to estimate the height of a steady-state solar feature relative to the photosphere, based on its apparent motion in the image plane recorded over severa…
