SUPERNOVA 2007ft in NGC 4677
     J. Isler, Fisk University; K. van der Heyden and B. A. Bassett,
South African Astronomical Observatory (SAAO); L.-G. Strolger, Western
Kentucky University; and R. A. Knop, Vanderbilt University, report
that a spectrum (range 420-700 nm) of 2007ft (cf. CBET 1004), obtained
on July 17.79 UT with the SAAO Radcliffe 1.9-m telescope (+ CCD with
grating spectrograph), shows it to be a type-Ia supernova within 1 day
of maximum light.  Cross-correlation with a library of supernova spectra
indicates that 2007ft is similar to the type-Ia supernova 1986G.
Removing the NED recession velocity of 3107 km/s for the host galaxy,
the minimum of the 635.5-nm Si II absorption is blueshifted by roughly
10500 km/s.
