Ellerman bomb

In solar physics, Ellerman bombs are intense, small-scale brightenings in the Sun's photosphere.

Intense brightenings resembling what would later be referred to as Ellerman bombs were first reported by Walter M. Mitchell in 1909.

[2] In 1917, observations of this phenomenon made at the Mount Wilson Solar Observatory were described in detail by Ferdinand Ellerman.

This interaction is suggested to result in magnetic reconnection, producing the brightenings associated with Ellerman bombs.

[1][5][6][7] The lack of observed brightening of the Hα core is attributed to Ellerman bombs being a photospheric phenomenon.
