We report the discovery of an optical transient in M31 from unfiltered
CCD images taken around Aug. 6.3 UT (about 18.1 mag) and Aug. 8.3
(about 17.6 mag) by the 0.45m ROTSE-IIIb telescope at the McDonald
Observatory. The nova candidate is located at RA = 00h40m54.4s DEC =
+40o53'50.3" (J2000), which is 20' 39.3" west and 22' 18.2" south of
the core of M31. TSS J004054.4+405350 was not detected in ROTSE-IIIb
data from Jul. 25.44 UT (limiting mag about 18.5). A finding chart for
the transient can be found at: http://grad40.as.utexas.edu/~quimby/tss/charts/nova14.png
