Relationship of type III radio bursts with quasi-periodic pulsations in a solar flare [PDF]

, 2016
We studied a solar flare with pronounced quasi-periodic pulsations detected in the microwave, X-ray, and radio bands. We used correlation, Fourier, and wavelet analyses methods to examine the temporal fine structures and relationships between the time ...

Space storm measurements of the July 2005 solar extreme events from the low corona to the Earth

, 2010
The Athens Neutron Monitor Data Processing (ANMODAP) Center recorded an unusual Forbush decrease with a sharp enhancement of cosmic ray intensity right after the main phase of the Forbush decrease on 16 July 2005, followed by a second decrease within ...

On the relationship of shock waves to flares and coronal mass ejections

, 2011
Context: Metric type II bursts are the most direct diagnostic of shock waves in the solar corona. Aims: There are two main competing views about the origin of coronal shocks: that they originate in either blast waves ignited by the pressure pulse of a ...

Electron acceleration and transport in the 2023-03-06 solar flare

Frontiers in Astronomy and Space Sciences
We investigated in detail the M5.8 class solar flare that occurred on 2023-03-06. This flare was one of the first strong flares observed by the Siberian Radioheliograph in the microwave range and the Advanced Space-based Solar Observatory in the X-ray ...
