[vsnet-alert 5871] Re: SN 2001bf in MCG +04-42-22

Dear SN watchers,

  We have submitted a report about the spectroscopy of SN 2001bf to
CBAT.  It is of type Ia near maximum. 

SUPERNOVA 2001bg in NGC 2608
     H. Kawakita, K. Kinugasa, Gunma Astronomical Observatory (GAO),
and H. Yamaoka, Kyushu University, report: "The low-resolution
spectrum (coverage 380-750 nm) of SN 2001bg (IAUC 7621) was taken with
GAO 0.65-m telescoope on May 10.93 UT.  The preliminary reduction
shows that this SN is of type Ia near the maximum light.  Adopting the
NED recession velocity of 2135 km/s for NGC 2608, the SN expansion
velocity, measured from Si II absorption minimum (rest 635.5 nm), is
9700 km/s.  Note that NGC 2608 had also produced SN 1920A, which
caught at m_pg = 11.8." 

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
