Abstract
Chandra observations on Jan 16, 2002 surveyed M31 with a series of 5 short (1ks) HRC images. Preliminary analysis yields the following info on new transients and highly variable sources: A new source CXOU J004307.0+411809 (RA=00h43m07s.099, DEC=+41o18'09".95, +/- 1", J2000) is discovered at a luminosity of 2.7 x 1037 ergs/sec (emitted over 0.3-7.0 keV, assuming a power-law spectrum with photon index=2 and NH = 1021 cm-2 at a distance of 780 kpc).
