SUPERNOVA 2008fv IN NGC 3147
     S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki
(Teppo-cho, Yamagata) of an apparent supernova (mag 16.5) on numerous
unfiltered 20-s CCD frames (limiting mag 19.0) exposed around Sept. 27.78
UT with a 0.60-m f/5.7 reflector.  The new object is located at R.A. =
10h16m57s.28 +/- 0s.01, Decl. = +73o24'36".4 +/- 0".2 (equinox 2000.0),
which is 16" east and 34" north of the center of the galaxy NGC 3147
Additional magnitudes from Itagaki for 2008fv:  2007 Feb. 2, [19.0; 2008
Sept. 10.80, [18.5; 28.569, 16.1.  Nothing is visible at this position on
the Digitized Sky Survey.  Following posting on the Central Bureau's
unconfirmed-objects webpage, C. Jacques and E. Pimentel, Belo Horizonte,
Brazil, write that an unfiltered 180-s CCD image (limiting mag 18.0)
taken on Sept. 28.49 -- remotely with a 30-cm f/9.1 reflector at the Gras
Observatory near Mayhill, NM, U.S.A. -- yields mag 15.6 and position end
figures 57s.27, 36".5 for 2008fv, adding that nothing is visible at this
position on a Digitized Sky Survey image from 1991 Dec. 6 (limiting red
magnitude 19.5).  Itagaki also discovered the type-Ib supernova 2006gi
in NGC 3147 (cf. IAUC 8751, 8755; CBET 635).
