We have detected a bright (V ~ 13) optical transients in the Catalina
Sky Survey (CSS)    with the Mt. Bigelow 0.8m Catalina Schmidt Telescope
on 18 Dec 2007 UT.    The transient is unresolved, and at the following
J2000 coordinates:   

<table>   <tr><td>   <a href='http://www.cacr.caltech.edu/~ajd/CSS_ATEL/712180180624111439.html'>CSS

The object is on the edge of a spiral arm of the Antennae Galaxies and
is consistent with    a supernova at this distance. The set of CSS discovery
observations consists of four images    spanning approx 20 minutes. The
transient was detected in all images and is constant in    magnitude and
position over the time span of the images. The object does not match the
location of any known asteroid. The source is not seen in archival CSS
or HST images.      

All stationary CSS optical transients are detected and published as
VOEvents in real-time    at http://voeventnet.org/feeds/Catalina.shtml
