We report the discovery of an optical transient in M31 from unfiltered
CCD images taken around Oct. 31.09 UT (about 16.4 mag) and Nov 1.08
(about 16.7 mag) by the 0.45m ROTSE-IIIb telescope at the McDonald
Observatory. The object is located at RA = 00h39m27.38s DEC =
+40o51'09.8" (J2000), which is 37' 0.4" west and 24' 58.7" south of
the core of M31. TSS J003927.3+405109 was not detected in ROTSE-IIIb
data from Oct 29.08 UT (limiting mag about 17.3). A finding chart for
the transient can be found at: http://grad40.as.utexas.edu/~quimby/tss/charts/nova11.png
