The single detected source, 1E 1339.8+2837, located in M3 (NGC 5272), was observed both in the ROSAT all-sky survey (Verbunt et al. 1994, 1995), and in pointed observations using the HRI (Hertz, Grindlay & Bailyn 1993). Estimates of the temperature and bolometric luminosity based on the all-sky survey were k T ,,~ 45 eV, and L ,-~ 10 a5 erg s -1. The source is a transient. Note that the inferred luminosity (though uncertain) is smaller than typical for SSSs found in the Galaxy, the Magellanic Clouds, and M31.
