EXO0748-676, a low mass X-ray binary system that shows regular total X-ray eclipses with a period of 3.82 hours, until August 2008 maintained a relatively steady X-ray flux of ~8 mcrab implying a luminosity of ~1.3E36 ergs/s (2-10 keV) at a distance of 7.7 kpc (Wolff et al. 2005, ApJ, v.632, p.1099). It began to fade in brightness during August-September 2008 (Wolff et al. Atel#1736). A Swift X-Ray Telescope (XRT) observation done on September 28, 2008 found a faint, soft X-ray source at the position of EXO0748-676 with a flux of approximately 1.2E-12 ergs/cm^2/s (0.5-5.0 keV ) corresponding to a luminosity of approximately 8.5E33 ergs/s at 7.7 kpc.
