We report the discovery of a transient in M31 using unfiltered CCD images
taken on June 15.38 UT (about 15.8 mag) and June 16.38 (about 16.6 mag)
using the 0.45m ROTSE-IIIb telescope at the McDonald Observatory. The
object is located at RA = 00h45m05.28s DEC = +41o33'40.1" and was not
detected in ROTSE-IIIb data from June 8.41 UT (limiting mag about 17.7).
The transient is consistent with a fast nova (cf. Figure 2 of della Valle
1991, A&A, 252, L9). A finding chart for the transient can be found
