[vsnet-campaign-sn 638] SN II 2003gd in M 74

Dear SN watchers,

  According to IAUC 8150, R. Evans visually discovered a bright (mag
about 13.2) SN in M 74, which has produced a 'hypernova' SN 2002ap
last year.  The new object turned to be a type II SN.

  The discovery was made on June 12.82 UT, in the twillight at
Australia.  The precise position measured from the image taken on the
next night with 1.0-m Siding Spring Observatory is:

R.A. = 1h36m42s.65, Decl. = +15o44'20".9 (J2000.0),

which is about 13" east and 161" south of the center of the spiral
galaxy M74 (=NGC 628).  There is a foreground star (red mag 12.4) with
the position end figures 32s.00, 45'08".7.

  The first spectrum was taken on the same night at America, i.e. June
13.46 UT = 0.64 days after discovery.  The IR spectrum shows a series
of strong and broad hydrogen Paschen emission lines, which indicates
that is it a type II SN around maximum.  The explosion can occured
when it was behind the Sun.  We are possibly able to enjoy the bright
SN for some weeks.  

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
