Rapid analysis of ROTSE-III sky patrol fields reveals a new CV which we
designate ROTSE3 J16134+012124.4. The object was first detected Apr. 13.37,
2005 by the ROTSE-IIIb telescope at McDonald Observatory, Texas, at an
unfiltered magnitude of 17.5. Follow-up observations over the following 18
hours with ROTSE-IIIa (at Siding Spring Observatory, Australia) and ROTSE-IIIc
(at the H.E.S.S. site in Namibia) show the transient fading over half a day to
m_R=17.9 on Apr. 13.64. It remained around m_R=18 through our most recent
observation on Apr. 14.07. The transient has a quiescent counterpart marginally
detected in the USNO-B1.0 catalog at m_R~20.4. A spectrum (430-890 nm)
obtained on Apr. 13.44 with the 9.2m Hobby*Eberly Telescope (+ Marcario
Low-Resolution Spectrograph) by J. Caldwell and E. Terrazas shows a blue
continuum with prominent H-alpha and H-beta emission. We therefore conclude
this is a galactic CV. Further information including a light curve and spectrum can be
found at http://www.rotse.net/transients/j1613/index.html .
