We report the discovery of 3 previously unseen X-ray point sources detected in a 5ks Chandra/ACIS observation starting on 2007-07-31.14 UT as part of our ongoing Chandra/HST M31 transient program. The sources were detected at the edge of the FoV, on the ACIS-S chips, which explains the larger than usual positional errors. Notes: - All coordinates are subject to the standard bore-sight correction, which in our case is less than our centroiding errors.
