An interpolation/extrapolation approach to X-ray imaging of solar flares
Inverse Problems and Imaging, 2012 We describe an interpolation/extrapolation procedure that reconstructs X-ray maps of solar flares using as input data sparse samples of the Fourier transform of the radiation flux, named visibilities. The algorithm is based on two steps: in the first step the performance of an interpolation routine is optimized by representing the visibilities ...

Forecasting Solar Energetic Particle (SEP) events with Flare X-ray peak ratios
Journal of Space Weather and Space Climate, 2018 Solar flare X-ray peak fluxes and fluences in the 0.1–0.8 nm band are often used in models to forecast solar energetic particle (SEP) events. Garcia (2004) [Forecasting methods for occurrence and magnitude of proton storms with solar soft X rays, Space ...

Solar Flare X-Ray Measurements and Their Relation to Microwave Bursts [PDF]
Symposium - International Astronomical Union, 1975 This review discusses the available observational material of solar hard X-ray bursts, their interpretation in terms of a model of the source region and their relation with other flash-phase phenomena, in particular the impulsive microwave bursts.

A Statistical Study of Soft X-Ray Flares on Solar-type Stars
The Astrophysical JournalThe statistical characteristics of stellar flares at optical bands have received extensive study, but they remain to be studied at soft X-ray bands, in particular for solar-type stars.

E3S Web of Conferences, 2018 Intense X-ray fluxes during solar flares are known to cause enhanced ionization in the Earth’s ionospheric D, E and F region. This sudden change of ionospheric electron density profile is serious problem to radio wave communication and navigation system.

Statistics of Solar White-light Flares. I. Optimization and Application of Identification Methods
The Astrophysical JournalWhite-light flares (WLFs) are energetic activity in the stellar atmosphere. However, observed solar WLFs are relatively rare compared to stellar WLFs or solar flares observed at other wavelengths, which limits our further understanding of solar/stellar ...
