SN 2009ao (disc. 2009/02/04.12) |
IIP |
16.6CR (Apr, 13.852) |
Spectra (range 402.7-1011 nm, Mar. 16.1-16.2): SN 2009ao is a young type-IIP supernova around a week past explosion; adopting a host-galaxy recession velocity of 3339 km/s (Chengalur et al. 1993, Ap.J. 419, 30) for the host galaxy (NGC 2939), H_beta is measured to be blue-shifted by roughly 8000 km/s. (CBET#1725)

The presumed host galaxy to 2009ar, SDSS J095525.67-012821.0, has Gunn magnitudes u = 23.2, g = 21.7, r = 21.5, i = 21.6, z = 21.9. SN 2009ar is a type-IIb supernova at z = 0.026 and is most like SN 1996cb at one day past maximum (Feb, 25). |

14:01:53.6 -01:20:30.2 |
17.25R (Mar, 25) |
Stritzinger, Morrell, and M. Phillips (also LCO) add that they have obtained spectra (range 403-1011.2 nm) of 2009Z (cf. CBET 1685) on Feb. 11.1 and 15.1 with the 6.5-m Magellan I (BAADE) telecope (+ IMACS). Cross- correlation with SNID shows these spectra to be most similar to those of SN 1993J at two days before and three days after maximum, respectively. |
