SN 2009ao (disc. 2009/02/04.12)

IIP

09:38:08.54

+09:31:00.7

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).

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.
