## Abstract

A concrete example of lump solution in bosonic open string field theory is presented and discussed. It is shown that the solution satisfies the equation of motion and is not a pure gauge. The expression of its energy is written down explicitly. The value of the energy, calculated both numerically and analytically turns out to be in agreement with that of a D24 brane tension.
