We present results of picture processing of the core of the globular cluster NGC 6624. The results are interpreted primarily in terms of the cluster's association with the X-ray aburst source 3U 1820--30. Possible optical counterparts for the burst source are suggested very near the visible nucleus of the cluster. We derive the visual magnitudes and colors (B-V) of these objects. Color maps in (b-v) and (u-b) are also given for the cluster core.
