COMPTEL solar flare measurements [PDF]
, 1996 We review some of the highlights of the COMPTEL measurements of solar flares. These include images of the Sun in γ rays and neutrons. One of the important features of the COMPTEL instrument is its capability to measure weak fluxes of γ rays and neutrons ...

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 ...

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.

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 ...

MULTI-WAVELENGTH OBSERVATIONS OF A LARGE SOLAR FLARE
Odessa Astronomical Publications, 2019 We present the results of the multi- wavelength study of the two-ribbon solar flare on July 19, 2000 in the active region NOAA 9087. The evo- lution and morphological properties of the flare pro- ductive active region have been analyzed.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) have long been a subject of interest in ionospheric research. However, their spatiotemporal variability across regions, local times, seasons, and solar cycles is very complicated and remains not well established.

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,

The Chinese Radio Telescope Array for Interplanetary Scintillation Monitoring
Space Weather, Volume 24, Issue 1, January 2026.Abstract Solar flares, coronal mass ejections (CMEs) and enegertic particles, etc., are the driving sources that may cause catastrophic space weathers. It is desirable to obtain information of solar eruptions like flares and CMEs, etc., propagating from the Sun to the near‐Earth space.

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.
