Sunspot waves and flare energy release
R. Sych, M. Karlický, A. Altyntsev +2
We address a possibility of the flare process initiation and further maintenance of its energy release due to a transformation of sunspot longitudinal waves into transverse magneti…
Multi-height observations of magnetoacoustic cut-off frequency in a sunspot atmosphere
Ding Yuan, R. Sych, V. E. Reznikova +1
We used the Pixelised Wavelet Filtering (PWF) method to compute narrow-band power maps of SDO/AIA imaging datasets in the 1700 Å, 1600 Å and 304 Å bandpasses that correspond to dif…
Spectral and spatial observations of microwave spikes and zebra structure in the short radio burst of May 29, 2003
G. P. Chernov, R. A. Sych, N. S. Meshalkina +2
The unusual radio burst of May 29, 2003 connected with the M1.5 flare in AR 10368 has been analyzed. It was observed by the Solar Broadband Radio Spectrometer (SBRS/Huairou station…
Frequency drifts of 3-min oscillations in microwave and EUV emission above sunspots
R. Sych, T. V. Zaqarashvili, V. M. Nakariakov +3
We analyse 3-min oscillations of microwave and EUV emission generated at different heights of a sunspot atmosphere, studying the amplitude and frequency modulation of the oscillati…
Three-minute oscillations above sunspot umbra observed with SDO/AIA and NoRH
V. E. Reznikova, K. Shibasaki, R. A. Sych +1
Three-minute oscillations over sunspot's umbra in AR 11131 were observed simultaneously in UV/EUV emission by SDO/AIA and in radio emission by Nobeyama Radioheliograph (NoRH). We u…
