Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

A 50–55 GHz Millimeter-wave Radiometer Spectrometer for Solar Flare Detection

The Astrophysical Journal Supplement Series
During solar flare eruptions, millimeter-wave radiation is emitted, which is highly efficient and sensitive to high-energy electrons, allowing for the extraction of unique magnetic field information.

Solar Radio Bursts in Relation to Flare Importances.

The Astrophysical Journal, 1963
S>The association solar radio bursts over the frequency range 200 to 9400 Mc with solar flares of different importances is investigated. Percentage association is highest at a frequency of about 4000 Mc, except for 3/sup +/ flares, in which the maximum association remains oonstant within the frequency range 1000- 5000 Mc. Centimeter bursts are found to

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.

Geomagnetic Storms and Related Solar Phenomena (a. Precipitating Particles and Auroras) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)

Antarctic Record, 1980
This is an attempt to identify the causes of geomagnetic storms which occurred during a year and a half from January 1977 to June 1978. The assignment of geomagnetic storm causation to appropriate coronal holes or solar flares has been made by ...

Forecasting SEP Atmospheric and Space Radiation by Coupling UMASEP and NAIRAS Models

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS) model predicts the radiation environment from the Earth's surface to free‐space. The model output provides dosimetric and particle flux quantities required to assess the hazardous radiation impacts to human health and adverse effects on vehicle electronic systems.

Advection-nonlinear-diffusion Model of Flare Accelerated Electron Transport in Type III Solar Radio Bursts

The Astrophysical Journal
Electrons accelerated by solar flares and observed as type III solar radio bursts are not only a crucial diagnostic tool for understanding electron transport in the inner heliosphere but also a possible early indication of potentially hazardous space ...
