The classifications given above are uncertain and are likely to improve as additional observations are taken. All of these transients have been detected by CSS on more than one night with the exception of CSS080409:174714+150048. All CSS optical transients are routinely compared to images and photometry from the following sources: the Sloan Digital Sky Survey (SDSS), the Palomar-Quest survey (PQ), DSS1+2, USNO-B and 2MASS. CSS080408:093516+171953 appears to be associated with radio source MG1_J093518+1719. Follow-up is requested.

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