Applied Sciences, 2021 Strong radiation from solar X-ray flares can produce increased ionization in the terrestrial D-region and change its structure. Moreover, extreme solar radiation in X-spectral range can create sudden ionospheric disturbances and can consequently affect ...

Sensing the Earth’s low ionosphere during solar flares using VLF signals and goes solar X-ray data [PDF]
, 2014 An analysis of D-region electron density height profile variations, induced by four isolated solar X-ray flares during period from September 2005 to December 2006, based on the amplitude and the phase delay perturbation of 22.1 kHz signal trace from ...

Temporal aspects and frequency distributions of solar soft X-ray flares [PDF]
, 2002 A statistical analysis of almost 50 000 soft X-ray (SXR) flares observed by GOES during the period 1976–2000 is presented. On the basis of this extensive data set, statistics on temporal properties of soft X-ray flares, such as duration, rise and decay ...

Cold Solar Flares. I. Microwave Domain
The Astrophysical Journal, 2023 We identify a set of ∼100 “cold” solar flares and perform a statistical analysis of them in the microwave range. Cold flares are characterized by a weak thermal response relative to nonthermal emission.

Habitat of early life: Solar X‐ray and UV radiation at Earth's surface 4–3.5 billion years ago [PDF]
, 2007 [1] Solar X-ray and UV radiation (0.1–320 nm) received at Earth's surface is an important aspect of the circumstances under which life formed on Earth.

Quality and Reliability Engineering International, EarlyView.ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.

Wavelet Analysis of Solar Flare Hard X‐Rays
The Astrophysical Journal, 1998 We apply a multiresolution analysis to hard X-ray (HXR) time profiles f(t) of solar flares. This method is based on a wavelet transform (with triangle-shaped wavelets), which yields a dynamic decomposition of the power at different timescales T, the scalogram P(T, t).

Patterns of X-Ray and γ-Ray Flares: From Blazar to Magnetar and Sun
The Astrophysical JournalUsing Gaussian process methods, we analyzed the light curves of three extreme solar X-ray flares observed by the RHESSI satellite. Their variability characteristics were then compared with those of HXMT-HE X-ray burst (XRB; in SGR 1935+2154) associated ...

Probability Distribution Functions of Solar and Stellar Flares
Physics, 2022 The paper studies the soft X-ray data of solar flares and found that the distribution functions of flare fluence are successfully modeled by tapered power law or gamma function distributions whose power exponent is slightly smaller than 2, indicating ...
