The Catalina Real-time Transient Survey has discovered seven supernova candidates from
CSS images and Palomar-60 follow-up between UT dates Dec 20th and Jan 26th. The
detections have the following parameters:
CSS090126:093230+174119 appears associated with galaxy 2MASX_J09323134+1741326 which has SDSS Gunn
mags (u=17.9, g=16.3, r=15.7, i=15.4, z=15.2) and spectroscopic redshift z=0.049.
CSS090125:112317+101741 is associated with an SDSS galaxy with mags (23.9, 22.3, 22.2, 21.9, 21.4).
CSS090120:164659+272759 is associated with an SDSS galaxy with mags (22.2, 22.0, 21.5, 21.3, 21.0).
CSS090102:115111+244022 is associated with an SDSS galaxy with mags (22.9, 21.6, 21.3, 21.0, 21.4)
in a galaxy cluster at z=0.13.
CSS090102:130037+175057 has no apparent host galaxy in SDSS, PQ, or DSS data.
CSS081229:134527-104353 has a possible faint source seen in deep CSS coadds but not PQ coadds,
as well as a possible detection in DSS2-B. This suggests the object might be a CV. However,
follow-up observations colours were more consistent with young SN-Ia.
CSS081220:021652+135500 is associated with a faint source seen in SDSS data. Follow-up
observations exhibited a colour consistent with young SN-Ia.
We request photometric and spectroscopic follow-up.
