Scientific paper

A bright X-ray transient in M31 was detected in a 5000-sec Chandra ACIS-I observation on 2001 Aug 31.54 UT. The new transient (CXOU J004305.5+411703) is located at R.A. = 00h43m05s.55, Decl = +41o17'03''.3 (equinox 2000.0; based on the aspect solution, with uncertainty of ~1''). The energy spectrum can be fitted with a power-law model with a photon index of 1.5; the 0.5-10 keV luminosity is estimated to be 2.7 x 1038 erg/s (assuming a distance of 780 kpc).
