(IAAC) Fwd: SN 2003gd in M74
This message came over the Webb Society's email list this morning...
A brightish SN in a very well-known galaxy - this is exciting news!
(Even more exciting for us curmudgeonly visual SN hunters - this
one was found by the venerable Rev. Evans with just his eyeballs
and his redoubtable 12" telescope! :->)
Clear skies,
Lew Gramer

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.
