SUPERNOVA 2009ep IN NGC 5329
     K. Kinugasa, S. Honda, H. Takahashi, H. Taguchi, and O. Hashimoto,
Gunma Astronomical Observatory (GAO); and H. Yamaoka, Kyushu University,
write that a low-resolution spectrum (range 400-800 nm, resolution about 500)
of 2009ep (cf. CBET 1805), was obtained on May 20.6 UT with the GAO 1.5-m
telescope (+ GLOWS).  The spectrum shows it to be a type-Ia supernova within
one week after maximum light.  Adopting the NED recession velocity of 7109
km/s for NGC 5329 (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 10000 km/s.
