Re: X-ray transients in M31 > XMMU J004438.1+414511 00 44 38.1 +41 45 11 (4") The third source is located close to the known ROSAT source RX J0044.6+4145. Although I feel (from the description in IAUC) that the identity has already been disproved, observers should carefully avoid any source confusion.
