We have detected an optical transient in Catalina Sky Survey (CSS) images obtained
with the Catalina Schmidt Telescope on 8 Jun 2008 UT. The transient is unresolved,
and at the following J2000 coordinates:
For finding charts and discovery images please see: http://voeventnet.cacr.caltech.edu/feeds/ATEL/CSS.
The object is near the edge of galaxy MAPS-NGP O_379_0244547 (z=0.043, g ~ 17.86, r ~ 17.48, i ~ 17.21 (SDSS)).
The transient is consistent with a Supernova. The CSS discovery observations consist of four images
spanning ~ 30 minutes. No transients are present in earlier epochs of CSS imaging including data taken
on the 29th April UT (to mag ~21), or prior DSS, PQ and SDSS images to mag ~23.
Follow-up would be appreciated.
Additional candidate and confirmed CSS SNe can be found
here.
