In solar physics, Ellerman bombs are small-scale intense brightenings in the Sun's photosphere. They typically take place in areas with strong magnetic fields and near emerging flux regions.[2][1][3] They are named after Ferdinand Ellerman[4] who studied them in detail in the 20th century. The phenomenon was first reported by W. M. Mitchell in early 1900.[5] Although Ellerman first described them in 1917,[6] the physical mechanism behind them is still debated.
Ellerman wrote about the bombs that "they seem to follow one another like the balls of a Roman candle". EB are short-lived, and last for few minutes.[1]
