Solar Activity Studies using Microwave Imaging Observations [PDF]
, 2016 We report on the status of solar cycle 24 based on polar prominence eruptions (PEs) and microwave brightness enhancement (MBE) information obtained by the Nobeyama radioheliograph.

DIAGNOSTICS OF PLASMA JETS IN THE SOLAR CORONA
Solar-Terrestrial Physics, 2021 The paper discusses the diagnostics of plasma jets in the solar corona with the use of data from modern space- and ground-based telescopes observing the Sun in the extreme ultraviolet (EUV) and micro- wave bands.

Multilevel Analysis of Oscillation Motions in Active Regions of the Sun [PDF]
, 2011 We present a new method that combines the results of an oscillation study made in optical and radio observations. The optical spectral measurements in photospheric and chromospheric lines of the line-of-sight velocity were carried out at the Sayan Solar ...

Identification of Super- and Sub-critical Regions in Shocks driven by Coronal Mass Ejections [PDF]
, 2011 In this work, we focus on the analysis of a CME-driven shock observed by SOHO/LASCO. We show that white-light coronagraphic images can be employed to estimate the compression ratio X = rho_d / rho_u all along the front of CME-driven shocks.

Radioheliograph array for the solar atmospheric dynamics [PDF]
SCIENTIA SINICA Physica, Mechanica & Astronomica, 2019 Studying the origin of solar activities, revealing the basic laws of solar activities and forecasting the violent solar eruptions are not only important problems in astronomy, but also the basis of protecting the near-Earth space environment and the many high-technology systems.

CORONAL JETS AS A CAUSE OF MICROWAVE NEGATIVE BURSTS
Solar-Terrestrial Physics, 2020 We have investigated the cause of three “isolated” negative radio bursts recorded one after another at several frequencies in the 1–17 GHz range at the Nobeyama Radio Observatory, Ussuriysk Astrophysical Observatory, and Learmonth Solar Observatory on ...
