Quimby et. al., The Nearby Supernova Factory and others have reported on Astronomical Telegram 658 their discovery of an optical transient using unfiltered CCD images taken on 2005 November 16.1 UT (about 15.5 mag) and November 17.1 (also about 15.5 mag) using the 0.45m ROTSE-IIIb telescope at the McDonald Observatory. The object is located at RA 02h 22m 16.4s DEC +41 22'59.9" (2000). TSS J022216.4+412260 was not detected in ROTSE-IIIb data from November 15.1 UT (limiting mag about 16.5). The Nearby Supernova Factory adds that a spectrum obtained November 18.6 UT on the University of Hawaii 2.2-meter telescope, shows it to be a dwarf nova in outburst. The spectra reveal a blue continuum with prominent H-alpha and HeII 4686 emission lines.
