| Abstract : | Our investigation focuses on an M-class solar flare occurring on November 29th, 2020, with the aim of comprehending the energy dynamics driving this event. We specifically delve into the thermal energy content and its temporal evolution during the flare, along with how the contribution of thermal energy to the overall energy budget changes over the course of the event. To quantify the bulk thermal energy of this flare, we use observations from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamic Observatory (SDO) and the Hinode X-ray Telescope. The differential emission measure (DEM) method is employed to estimate thermal energy as a function of time. In parallel, our analysis leverages spectra obtained from the Fermi satellite to gain insights into the evolution of non-thermal energy during the flare. Notably, this flare exhibits a fan structure and Supra Arcade Downflow (SADs). A segment of the flare arcade appears notably hotter than the surrounding area, accompanied by spatial variations in the cooling of the fan. We study the evolution of the loop top hard X-ray source in comparison to the thermal evolution of the fan. We also study the effects of the SADs on the thermal evolution of the fan. |
