Andrew Howell, Curtis McCully, Stefano ValentiLCOGT SN-KPSN Ia0.031LCOGT SN-KPUsing Superfit (Howell et al. 2005, ApJ, 634, 1190), we find good fits to several normal Type Ia supernovae about a week before maximum light at the redshift of the host galaxy (z=0.03, derived from the narrow H-alpha line in the spectrum), but with fits as early as -15 days and as late as -1 day. The 0.5 mag/day rise from ASAS-SN favors an earlier phase, while the current absolute magnitude (M_V ~ -19 mag) favors a phase closer to peak.

The spectrum shows strong Balmer and Fe II lines with P-Cygni profiles characteristic of a Type II SN, with strong host galaxy contamination (including nebular emission lines). After correcting the spectrum for the redshift of the host galaxy, we measure an expansion velocity from the H-alpha line of 5800 km/s from the minimum of the P-Cygni trough

Andrew Howell, Iair Arcavi, Curtis McCully, Stefano ValentiLCOGT SN-KPSN Ia0.0341LCOGT SN-KPFrom extended H-alpha emission in the 2D spectrum, we derive a redshift of z=0.034 for the host galaxy. At this redshift, the absolute magnitude at discovery was M_V = -19.0 mag. Using Superfit (Howell et al. 2005, ApJ, 634, 1190), we find a good fit to the normal Type Ia SN 2002bo 1 day before maximum light.

The spectrum shows features consistent with a Type Ia SN around maximum light on top of strong host galaxy contamination. We measure Si II 6355 Angs. expansion velocity of 9800 km/s from the minimum of the P-Cygni absorption trough.

The spectrum is that of a normal SN Ia around maximum light with strong host-galaxy contamination. Using SNID, the best-fit template is SN2003ic at -4 days with respect to B-band maximum light.

The spectrum is characteristic of a normal SN Ia past peak with strong host galaxy contamination. Using SNID to fit the spectrum, the best fitting template is the normal SN Ia 2005hf at +9 days. After correcting the spectrum for the redshift of the host, we measure a Si II 6355 Angs. velocity of 8000 km/s.
