摘要：

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 0.3~ of the nominal pulsar position with V almost-equal-to 20. This magnitude is consistent with a main-sequence cluster member with M almost-equal-to 0.45 M.. However, this star may be blended with fainter stars, and the probability of a chance superposition is nonnegligible.
