We have detected the optical brightening by ~3 mags (V ~ 16.8) of a previously known radio source (~ flat-spectrum, unknown redshift) in the Catalina Sky Survey (CSS) on 29 Dec 2008 UT.

CSS081229:104032+061721 2008-12-29 UT 10:22:05 10:40:31.61 06:17:21.8 812291070574110368

The discovery data and finding chart are posted at the CRTS VOEventNet webpage: http://voeventnet.caltech.edu/feeds/ATEL/CRTS/812291070574110368.atel.html (SDSS object ID 587732701792108700).

P60 colors from 30 Dec 2008 UT are consistent with a QSO at z < 2. Preliminary analysis of a P200 spectrum shows a featureless continuum, consistent with a blazar. Further analysis of the spectrum is in progress.
