SUPERNOVA 2009fu IN NGC 846
     K. Kinugasa, H. Takahashi, S. Honda, H. Taguchi, and O. Hashimoto,
Gunma Astronomical Observatory (GAO); and H. Yamaoka, Kyushu University,
write that a low-resolution spectrum (range 420-800 nm, resolution about 500)
of 2009fu (cf. CBET 1832) was obtained on June 11.8 UT with the GAO 1.5-m
telescope (+ GLOWS).  This spectrum most resembles that of a typical type-Ia
supernova about two weeks after maximum light.  Adopting the NED recession
velocity of 5118 km/s for NGC 846 (de Vaucouleurs et al. 1991, Third
Reference Catalogue of Bright Galaxies, ver. 3.9), the expansion velocity
derived from the Si II absorption minimum (rest 635.5 nm) is about 8000 km/s.
