Description

With the ongoing peak of the 25th solar cycle, the number of solar flare events is on the rise. This offers the perfect opportunity to study these phenomena in greater detail and understand the production and transport of high energy particles/radiations in interplanetary space. This is fundamentally important for space-weather predictions and protecting in-orbit assets. The multi-wavelength emission of energetic particles and photons during solar flare events provides an ideal natural laboratory for identifying precursors that could aid in predicting these powerful events.

In this study, we present the results of our analysis of Fermi-LAT observations of solar flare events over 17 years. Characterisation of the gamma-ray spectra for all solar flares since 2008 helps us distinguish different types of gamma-ray solar flares and helps us look for pre-cursor signals. We also extrapolate the best-fit spectra to the TeV/PeV energy range to test the prospect of observation with future Southern Wide-field Gamma-ray Observatory (SWGO) surface array detectors.
