We report the discovery of an optical transient near M31 using unfiltered CCD images taken on October 11.15 UT (about 16.7 mag) and October 12.12 (about 16.2 mag) using the 0.45m ROTSE-IIIb telescope at the McDonald Observatory. The object is located at RA = 00h44m20.7s DEC = +41o23'11" (J2000), which is 18' 6.6" east and 7' 2.5" north of the core of M31. TSS J004420.7+412311 was not detected in ROTSE-IIIb data from October 10.15 UT (limiting mag about 17.3).
