Online analysis of ROTSE-III sky patrol fields reveals a new CV we designate ROTSE3 J100932.2-020155. The object was first detected on 20 Jan 2005 by the ROTSE-IIIb telescope at McDonald Observatory, Texas at an unfiltered magnitude m_R = 14.3. It has since stayed brighter than m_R=15 and has been imaged by ROTSE-IIIa at Siding Spring Observatory, Australia and ROTSE-IIIc at the H.E.S.S. site in Namibia, with the most recent detection on 22 Feb. The 2df survey had targeted the object (m_b=20.5) as a possible quasar, and took two spectra. The spectra are consistent with a quiescent galactic CV. On 20 Feb we took a spectrum during outburst with the HET. The object has a blue continuum with prominent H-alpha emission. This object is consistent with a SU UMa Dwarf Nova during a super outburst.
