Description

Magnetic reconnections play a crucial role in shaping the dynamics of active regions in the solar atmosphere. It is a fundamental physical process where the reconfiguration of the magnetic field converts magnetic energy into kinetic and thermal energy. Magnetic reconnection events occur on different spatial scales, often associated with solar flares
and coronal mass ejections. At the smallest observable scale, magnetic reconnection manifests as Ellerman Bombs (EBs). These are small-scale, short-lived brightness enhancements on the outer
wings of optical lines, particularly the Balmer H$\alpha$ line at 6563 Å. Observations from the Swedish 1-m Solar Telescope (SST) have been widely used to study Ellerman bombs due to its high spatial resolution capabilities. Recent SST observations of Ellerman bombs have arguably provided some of the most detailed views on magnetic reconnection in astrophysical
plasmas. This work aims to gather high-quality statistics on Ellerman bombs, thereby enabling us to better characterize the conditions of magnetic reconnection in the deep solar atmosphere.
