A study of quasi-periodic fluctuations of solar microwave emission at the preflare stage is
presented. Data from daily solar observations by the Nobeyama Radioheliograph at a …

According to Tan et al.(2016), long-period (with a period P= 1.9‒47.3 min and a duration of
1‒2 h) quasi-periodic pulsations (QPPs) are observed in soft Х-rays before a significant …

We present a study of quasi-periodic pulsations in the microwave emission from solar active
region (AR) NOAA 12673, which produced the strongest flares of the 24th solar activity …

We present a study of the spatial distribution of quasi-periodic oscillations (QPOs) of
microwave emission in three solar active regions before flares. The following events are …

For the first time, several flare events are analyzed based on multifrequency observations
using the Radio Solar Telescope Network. The purpose of the analysis is to identify signs of …

We present a study of the frequency of occurrence of quasi-periodic fluctuations (QPFs) of
microwave radiation from solar active regions at the pre-flare stage. We used correlation …

We present a study of the spatial distribution of quasiperiodic oscillations of microwave
emission in two active regions before M-class flares. We have studied two events: NOAA …

In this study, a comparative analysis was carried out on the preflare and flare conditions for
six flares accompanied by coronal mass ejections (CMEs) and five events not accompanied …
