Abstract
The core of the globular cluster NGC 6624 has been imaged with the Hubble Space Telescope at three separate epochs. We report the detection of a dwarf nova in eruption at a distance of 5 core radii from the center of the cluster—one of the densest in the Galaxy. This is only the fourth dwarf nova detected in a globular cluster. Our temporal coverage implies that there are unlikely to be more than three dwarf novae in the cluster, unless globular cataclysmics erupt much less frequently than those in the field.Keywords
