Abstract

Our project involves a unique sample of 11 solar flare events observed by the space mission Solar X -ray Spectrometer (SOXS) particularly by CZT detector. We study temporal characteristics of 11 flares in general and rise time characteristics in particula r. For this purpose, we got an opportunity to learn newly developed software in IDL. The flares SELECTION is based on the GOES intensity in the range of M1.0 -X1.0. The catalogue of all the flares chosen for this work is presented in table. The rise time of flares vary between 123 and 433 secs in 4 -5.5 keV energy band while shortest rise time of the order of ~60 secs has been observed in 20 -56 keV high energy bands. We have discussed analysis methodology and results in Table. Our results reveal unique featur e that rise time decays exponentially towards high energy. This result suggests that short rise time at high energy tail may be due to faster acceleration of electrons and thereby producing non -thermal bremsstrahlung via collisions of electrons with ambien t plasma in solar flare loops.
