SUPERNOVA 2009P IN PGC 34730
     U. K. Gurugubelli, G. C. Anupama, D. K. Sahu, and A. Kaur, Indian
Institute of Astrophysics, Bangalore, report that a spectrum (range 360-750
nm) of 2009P (cf. CBETs 1674, 1680), obtained on Jan 30.5 UT with the Indian
Astronomical Observatory's 2-m Himalayan Chandra Telescope (+ HFOSC), shows it
to be a 1991T-like type-Ia supernova.  Using the SNID code (Blondin and Tonry
2007, Ap.J. 666, 1024), the spectrum of 2009P is found to be similar to that
of SN 1999aa about one day before maximum light.  Adopting a recession
velocity of 7526 km/s for the host galaxy (de Vaucouleurs et al. 1991, Third
Reference Catalogue of Bright Galaxies), the blue-shifted velocity of the Si
II 635.5-nm absorption is estimated to be approximately 14000 km/s.
