Solar Flare Prediction with the Hybrid Deep Convolutional Neural Network

Astrophysical Journal, 2019
We propose a hybrid Convolutional Neural Network (CNN) model (Model 2) and modify a popular CNN model (Model 1) to predict multiclass solar flare occurrence within 24 hr.

Solar Flare Modified Complex Network

Astrophysical Journal, 2020
A constructive approach is developed to build the solar flare complex network by utilizing a visibility graph condition alongside the Abe–Suzuki method. Solar flare information such as position, start time, and peak flux is used for this purpose.

Properties of Flares-Generated Seismic Waves on the Sun

, 2005
The solar seismic waves excited by solar flares (``sunquakes'') are observed as circular expanding waves on the Sun's surface. The first sunquake was observed for a flare of July 9, 1996, from the Solar and Heliospheric Observatory (SOHO) space mission ...

Analysis of Solar-like X-class Flare on Wolf 359 Observed Simultaneously with TESS and XMM-Newton

The Astrophysical Journal, 2023
We present an analysis of a flare on the Wolf 359 star based on simultaneous observations of Transiting Exoplanet Survey Satellite and XMM-Newton. A stellar flare with energy comparable to an X-class solar flare is analyzed on this star for the first ...

A Study of Solar Flare Effects on the Geomagnetic Field Components during Solar Cycles 23 and 24

Atmosphere, 2021
In this paper, we investigated the impact of solar flares on the horizontal (H), eastward (Y) and vertical (Z) components of the geomagnetic field during solar cycles 23 and 24 (SC23/24) using data of magnetometer measurements on the sunlit side of the ...
