Signatures of Confined and Eruptive Solar Flares in Microwave Spectra

The Astrophysical Journal
We describe how microwave spectra of confined flares differ from those of eruptive flares. All 29 confined ≥M1.4 soft X-ray flares from NOAA Active Region 12192 in 2014 October that were observed by the Radio Solar Telescope Network in the >300 MHz ...

Radio blips and hard X-rays in solar flares

The Astrophysical Journal, 1983
The properties of short, narrow-band spikes occurring in groups at decimetric wavelengths have been extensively analyzed. The bursts, termed blips in the literature, have been found to appear in the impulsive phase of flares. They are associated with hard X-ray emission in 40 percent of all cases with simultaneous coverage.

Unveiling the Interplanetary Solar Radio Bursts of the 2024 Mother’s Day Solar Storm

The Astrophysical Journal Letters
We report on a comprehensive study of interplanetary type III radio bursts linked to X-class solar flares from NOAA active region 13664, which instigated the intense 2024 Mother’s Day solar storm, marked by a geomagnetic storm of −412 nT, the strongest ...

Solar Radio Wide‐Band Spectroscopy and Imaging Facilities of the Chinese Meridian Project Phase II

Space Weather
Solar eruptions, including flares and coronal mass ejections, are the most energetic phenomena in the solar system. These explosive events accelerate high‐energy particles and generate electromagnetic radiation from radio to gamma‐ray wavelengths ...

Radio imaging of flares [PDF]

High resolution (arcseconds to ten of arcseconds) mapping of solar microwave bursts has recently been achieved. The properties of the radio images that have been reported and, so far as possible, the relation of the radio sources to X-ray observations of

Characteristics of events with metric-to-decahectometric type II radio bursts associated with CMEs and flares in relation to SEP events

, 2017
A gradual solar energetic particle (SEP) event is thought to happen when particles are accelerated at a shock due to a fast coronal mass ejection (CME).

A Study of Real-time Detection Methods for Solar Radio Burst Identification

The Astrophysical Journal Supplement Series
Solar flares, coronal mass ejections, and other solar radio burst phenomena release substantial amounts of solar radiation energy, resulting in adverse space weather conditions and posing significant hazards in space. Spectrum analysis conducted manually
