Determination of solar flares in radio flux and comparing the types of solar flares in x-ray region / Mohd Faiez Ali. [PDF]
, 2010 The Sun is one of the prominent features in our galaxy. The Sun itself has tremendous secrets that are still need to be study for example the energy in term of photon which is driven throughout the light which emitted from the Sun.

Space Weather, Volume 24, Issue 10, October 2026.Abstract Space weather events can significantly alter the ionospheric electron density, affecting signal transmission and navigation accuracy in satellite‐based systems. Consequently, there is an urgent need for reliable forecasting of the Thermosphere‐Ionosphere (TI) system.

Study of solar type-II radio bursts and H-α flares [PDF]
, 1992 97-100An analysis of the relationship of solar type-Il radio bursts with H-α flares has been presented. The study shows that 75% of type-II bursts is associated with bright H-α flares of importance ≤ 1.

The high-frequency characteristics of solar radio bursts
, 1992 We compare the millimeter, microwave, and soft X-ray emission from a number of solar flares in order to determine the properties of the high-frequency radio emission of flares.

Are there Radio-quiet Solar Flares?
, 2006 . Some 15 % of solar flares having a soft X-ray flux above GOES class C5 are reported to lack coherent radio emission in the 100 – 4000 MHz range (type I – V and decimetric emissions).

Microwave and Hard X-ray Emission Bursts during Solar Flares [PDF]
, 1987 384-389Analysis of time intervals and peak fluxes between hard X-ray (HXR) of energies 17-40 keV and solar microwave (MW) bursts observed at 3.75,9.4 and 17 GHz during impulsive and extended solar flares shows both simultaneous emission between MW and ...

Radio burst characteristics of solar proton flares
The Astrophysical Journal, 1982 To isolate the properties of solar radio bursts indicative of energetic (E>20 MeV) proton acceleration, we compare several groups of solar bursts. Intense centimetric bursts and metric type II bursts associated with solar flares at magnetically well-connected longitudes, but not resulting in detected prompt proton events, are compared with the radio ...

Statistical Study of Nine Months Distribution of Solar Flares
, 2014 Solar flare is one of the solar activities that take place in the outermost layer of the corona. Solar flares can heat the material to several million degrees in just a few minutes and at the same time they release the numerous amount of energy.

First Detailed MeerKAT Imaging Spectroscopy of a Solar Flare
The Astrophysical Journal LettersRadio observations provide powerful diagnostics of energy release, particle acceleration, and transport processes in solar flares. However, despite recent progress in radio interferometric imaging spectroscopy, current instruments still face limitations ...
