Abstract
We have searched deep optical images of the globular cluster M4 for a possible optical counterpart for the third body in the PSR B1620-26 system. We identify as a possible optical counterpart a star located within of the nominal pulsar position with . This magnitude is consistent with a main sequence cluster member with . However, this star may be blended with fainter stars, and the probability of a chance superposition is non-negligible.
