Solar Flare Intensity Prediction With Machine Learning Models
Space Weather, 2020 We develop a mixed long short‐term memory (LSTM) regression model to predict the maximum solar flare intensity within a 24‐hr time window 0–24, 6–30, 12–36, and 24–48 hr ahead of time using 6, 12, 24, and 48 hr of data (predictors) for each Helioseismic ...

Energy Landscape in Iraq: Current Status, Research Review, and Policy Insights
Energy Science &Engineering, Volume 14, Issue 1, Page 625-678, January 2026.Renewable energy currently contributes a small fraction to Iraq's electricity mix, with 3.39% from hydropower and 0.059% from solar, while thermal power dominates at 96.6%. Significant untapped potential exists across solar, wind, biomass, geothermal, wave, and blue energy, highlighting opportunities for a low‐carbon, technoeconomically viable energy ...

High-resolution Observations of a C9.3 White-light Flare and Its Impact on the Solar Photosphere
The Astrophysical Journal LettersWe present a detailed analysis of a C9.3 white-light flare using high-resolution observations from the New Vacuum Solar Telescope. The flare occurred near the eastern solar limb on 2023 September 11, within NOAA AR 13431, and produced beam electrons with

Microwave imaging of quasi-periodic pulsations at flare current sheet
Nature Communications, 2022 Quasi-periodic pulsations (QPPs) are frequently detected in solar and stellar flares, but the underlying physical mechanisms are still to be ascertained.

Solar Flare Occurrence Rate and Waiting Time Statistics
, 2012 We use Renewal Theory for the estimation and interpretation of the flare rate from the Geostationary Operational Environmental Satellite (GOES) soft X-ray flare catalogue. It is found, that in addition to the flare rate variability with the solar cycles,

Evaluation of Applicability of a Flare Trigger Model based on Comparison of Geometric Structures [PDF]
, 2018 The triggering mechanism(s) and critical condition(s) of solar flares are still not completely clarified, although various studies have attempted to elucidate them.

Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract High‐speed solar wind streams (HSS), originating from coronal holes (CH), are key drivers of space weather disturbances and heliospheric dynamics. However, forecasting HSS remains challenging due to the evolving morphology of CH. In this study, we present a deep learning‐based framework that models the spatiotemporal relationship between CH ...

The White-light Emissions in Two X-class Flares Observed by ASO-S and CHASE
The Astrophysical Journal LettersThe white-light continuum emissions in solar flares (i.e., white-light flares) are usually observed on the solar disk but, in a few cases, off the limb.

FEATURES OF THE DEVELOPMENT OF A CIRCULAR SOLAR FLARE
Odessa Astronomical Publications, 2020 We present the results of the analysis of morphology and evolution of the circular solar flare using H-alpha images. H-alpha filtergrams were obtained with the Meudon spectroheliograph.
