0131+15A SUPERNOVA 2003gd in NGC 628 (M74)
We have been informed by the Central Bureau for Astronomical Telegrams
(IAU Circular 8150) that Robert O.Evans, Hazelbrook, NSW, Australia,
visually discovered a supernova at magnitude 13.2 on June 12.82 UT on top
of the southern spiral arm of NGC 628 (M74), using a 0.31-m reflector.
SN 2003gd was confirmed by Robert H. McNaught, Australia National
University, at red magnitude 13.9 on images taken June 13.84 UT. McNaught
also measured a precise position (IAUC 8150) for the supernova, offset
13.2" east and 161" south of the galaxy center, as:
R.A. = 01h 36m 42.65s Dec = +15 degrees 44' 22.9" (2000.0)
Spectroscopy obtained June 13.46 UT in twilight by Peter Garnavich,
University of Notre Dame, and E. Bass, Cornell University, confirm the
object as a type-II supernova (IAUC 8150).
Observations reported to the AAVSO include:
V = 14.26 +/- 0.03 BRUCE GARY (GBL), HEREFORD, AZ.
SN 2002GD can be found indicated on the AAVSO chart for SN 2002ap,

Please report observations of 0131+15A SN 2003GD to the AAVSO, and be
certain to indicate which chart and comparision stars you used. For more
information on SN 2003gd, please see IAU Circular 8150.
Congratulations to Bob on his latest discovery!
