We report the discovery of an optical transient in M31 from unfiltered
CCD images taken on Sept. 18.14 UT (about 16.7 mag) by the 0.45m
ROTSE-IIIb telescope at the McDonald Observatory. The object is
located at RA = 00h42m42.3s DEC = +41o08'46" (J2000), which is 23.3"
west and 7' 22.4" south of the core of M31. TSS J004242.3+410846 is
about 6' south of the possible nova reported by Burwitz et al. (ATel
#884) and was not detected in ROTSE-IIIb data from Sept. 12.45 UT
(limiting mag about 16.9). A finding chart for the transient can be
