Rapid analysis of ROTSE-III sky patrol fields reveals a probable new CV which we designate ROTSE3 J212313-021446.6. The object was first detected Jun. 01.05, 2005 by the ROTSE-IIIc telescope at the H.E.S.S. site in Namibia, at an unfiltered magnitude of 16.8. It was detected 1 day later at an unfiltered magnitude of 16.9, which is our most recent observation of the transient. Observations from May 23 do not detect the source to a limiting magnitude of 17.5. Visual inspection of the POSS-II plate scans from USNO reveals a faint counterpart. The light curve during outburst and quiescent magnitude of this transient are very similar to other galactic CVs detected by ROTSE-III. We tentatively conclude that this is a galactic CV, although we require spectroscopic or multi-band confirmation. Further information including a light curve and image can be found at http://www.rotse.net/transients/j2123/index.html
