Supernova 2003gs in NGC 936.


Abstract (from CDS):

Hamuy also reports, with L. Gonzalez (Universidad de Chile), the following preliminary CCD magnitudes for SN 2003gs (cf. IAUC 8171) from data obtained with the Las Campanas Observatory Swope 1-m telescope: July 30.33 UT, B = 14.12, V = 13.46, I = 13.31; July 31.27, 14.23, 13.48, 13.30. These observations suggest that SN 2003gs is a few days past V maximum. The B-V colors (0.66 and 0.73) at these two epochs is much redder than the color displayed by normal type-Ia events near maximum light (B-V = 0) but is similar to that of the subluminous SN 1991bg (Leibundgut et al. 1993, A.J. 105, 301). A spectrum (range 390-900 nm), obtained as above by N. Morrell on July 31.33 with the Baade telescope, confirms that SN 2003gs is spectroscopically peculiar (cf. IAUC 8171, 8172). The lack of interstellar Na I D lines suggests that SN 2003gs is not significantly reddened by dust.
