Despite indications that classical cataclysmic variable (CV) stars are rare in globular clusters in general, and in the cluster NGC 6624 in particular, we have serendipitously discovered such a star ∼6" from the cluster center. A Hubble Space Telescope spectrum of the m∼22 object shows strong, broad emission lines typical of numerous field CVs, and the inferred optical and UV luminosity are also similar. Our accidental observation also provides the first high-quality ultraviolet spectrum of a globular cluster CV. That we have detected such an object in an observation that includes just a few percent of the central area of the cluster may indicate that cluster CVs are more common than previously thought, at least near the core.
