SUPERNOVA 2006it IN NGC 6956
     D. K. Sahu and G. C. Anupama, Indian Institute of Astrophysics,
report that a spectrum (range 350-920 nm) of SN 2006it (cf. CBET 660),
obtained on Oct. 8.73 UT with the Indian Astronomical Observatory's
2-m Himalayan Chandra Telescope (+ HFOSC), shows it to be a young
type-IIP supernova, a few days after the explosion.  The spectrum
shows a blue continuum with well-developed P-Cyg profiles of the
hydrogen Balmer lines H_alpha and H_beta.  The spectrum is similar to
that of SN 1999em (cf. IAUC 7294, 7296) a week past explosion (Leonard
et al. 2001, PASP 114, 35).  Adopting a recession velocity of 4650 km/s
for the host galaxy (de Vaucouleurs et al. 1991, Third Reference
Catalogue of Bright Galaxies), the minimum of the P-Cyg profile of
H_alpha indicates an expansion velocity of about 10000 km/s.
