Periodic Solar Flare X-ray Emission

Nature, 1971
GLENCROSS1 has reported the observation of an apparent 6 min periodicity during X-ray flares observed in the 0.1 to 0.3 nm wavelength band. The detector was a soft X-ray sensor on the satellite OSO-IV launch in 1967. The observed flare profiles were examined in more than thirty X-ray events coincident with visible flares, and a histogram was ...

Hard X-Ray Imaging of Solar Flares

2022
The idea for this text emerged over several years as the authors participated in research projects related to analysis of data from NASA's RHESSI Small Explorer mission. The data produced over the operational lifetime of this mission inspired many investigations related to a specific science question: the when, where, and how of electron acceleration ...

X-ray emission from solar flares

Journal of Astrophysics and Astronomy, 2008
Solar X-ray Spectrometer (SOXS), the first space-borne solar astronomy experiment of India was designed to improve our current understanding of X-ray emission from the Sun in general and solar flares in particular. SOXS mission is composed of two solid state detectors, viz., Si and CZT semiconductors capable of observing the full disk Sun in X-ray ...

Statistical properties of soft X-ray solar flares

AIP Conference Proceedings, 2003
We investigate some statistical properties of soft X‐ray bursts produced by solar flares. The Probability Density Functions (PDFS) of soft X‐ray intensity fluctuations are shown to display wide, non‐gaussian tails. The shape of the PDFs is nearly unchanged as the timelag, used to calculate fluctuations, varies. A very similar behavior is found for PDFs

Fast Transients in Hard X-ray Solar Flares

Solar Physics, 1983
We present the results of a search for fast spikes in 5483 hard X-ray solar flares as observed with the Hard X-Ray Burst Spectrometer on the Solar Maximum Mission (SMM). Hundreds of fast spikes with durations of less than 1 second have been detected at time resolutions of 128 ms and 10 ms.
