Abstract

The possibilities of using cubesat nanosatellites to detect the hard X-ray radiation (HXR) from solar flares are shown. The results of HXR measurements of several flares in the energy range >30 keV using the DeCoR-1 and DeCoR-3 instruments installed on the Avion satellite are presented, as well as a table of flares observed in HXR on the MSU constellation cubesats from September 2023 to February 2024.
