SN2003gh 20030607.707 <185CR MLF SN2003gh 20030629.737 157:C MLF SN2003gh 20030630.694 156C MLF # SN 2003gh (7:45:17.93, -71:24:37.3 (J2000.0), offset about 6"E) # is hosted by NGC 2466, a face-on spiral (SA(s)c:) galaxy. There is # a foreground star (mag about 16-7) superimposed on the eastern arm. # The position end figures of this star is about 18s.5, 33".1. The # magnitude at discovery is consistent with (or slightly brighter # than) the expected maximum of typical SN Ia. # # Additionally, on the DSS I-band image (taken on 1989 Dec. 17), the # central region of NGC 2466 appeared to elongated to the east, as if # an apparent supernova existed at the position end figures 16s.73, # 38".0. This region is overexposed on the DSS images on other bands, # so it is not certain that it is a transient or a permanent. Berto's # image will be helpful. -- "calcium-rich SNe" The UCB team reported that SN 2001co is a peculiar type Ib/c object; calcium lines are very strong, but oxygen feature is very weak or nearly absent which is very prominent on a later phase of the normal SNe Ib/c. The spectrum of SN 2003H, which was once classified to be a type Ib, became similar to that of SN 2001co. SN 2003dg and SN 2003dr are also of this class.
