Varying Calcium Abundances in Solar Flares seen by Solar Maximum Mission
Barbara Sylwester, Janusz Sylwester, Kenneth J. H. Phillips +1
We report on calcium abundance estimates during the decay phases of 194 solar X-ray flares using archived data from the Bent Crystal Spectrometer (BCS) on Solar Maxim…
Detection of the third innermost radiation belt on LEO CORONAS-Photon satellite around 2009 solar minimum
Oleksiy V. Dudnik, Janusz Sylwester, Miroslaw Kowalinski +2
We analyze variations of high-energy charged particle populations filling various magnetospheric regions under, inside, and outside of the Van Allen inner and outer electron radiat…
New Solar Flare Calcium Abundances with no Surprises: Results from the SMM Bent Crystal Spectrometer
J. Sylwester, B. Sylwester, K. J. H. Phillips +1
The calcium abundance in flare plasmas is estimated using X-ray spectra from the Solar Maximum Mission Bent Crystal Spectrometer (BCS) during the decays of 194 flares (GOES classif…
Four decades of advances from MSDP to S4I and SLED imaging spectrometers
P. Mein, J. -M. Malherbe, F. Sayede +3
The Multichannel Subtractive Double Pass (MSDP) is an imaging spectroscopy technique, which allows observations of spectral line profiles over a 2D field of view with high spatial…
A Unique Resource for Solar Flare Diagnostic Studies: the SMM Bent Crystal Spectrometer
J. Sylwester, B. Sylwester, K. J. H. Phillips +2
The Bent Crystal Spectrometer (BCS) on the NASA Solar Maximum Mission spacecraft observed the X-ray spectra of numerous solar flares during the periods 1980 February to November an…
A Search for High-Frequency Coronal Brightness Variations in the 21 August 2017 Total Solar Eclipse
P. Rudawy, K. Radziszewski, A. Berlicki +4
We report on a search for short-period intensity variations in the green-line FeXIV 530.3 nm emission from the solar corona during the 21 August 2017 total eclipse viewed from Idah…
