Abstract
A developing active region near the center of the solar disk was observed for 80 min at the center and the wings of Hα. Ellerman bombs lying both below an Arch Filament System and near sunspots were studied at Hα - 1.0 A and Hα - 0.75 A. We determined their average contrast, lifetime, size and we studied their flux as a function of time. We found evidence that the size of Ellerman bombs increases with height. The time curves of flux provide evidence for both impulsive and gradual energy release. Under the AFS the Ellerman bombs form a cellular pattern with a characteristic size of 3.1 × 103 km. Fifty percent of the bombs appear and disappear in pairs, possibly associated with bipolar emerging magnetic flux tubes.
