SUPERNOVAE 2004gq AND 2004gr

           Discoveries of two supernovae have been reported from
unfiltered CCD images:  SN 2004gq independently by H. Pugh and W.
Li (LOSS/KAIT; cf. IAUC 8448) and by F. Manzini (Novara, Italy,
0.4-m telescope; Stazione Astronomica di Sozzago Supernova Search),
and SN 2004gr by LOSS.

SN       2004 UT        R.A.  (2000.0)  Decl.    Mag.     Offset
2004gq   Dec. 11.36   5 12 04.81  -15 40 54.2   15.5   22".3 E, 22".4 N
2004gr   Dec. 11.57  11 26 15.02  +27 52 06.7   17.9   9".2 W, 5".5 N

The data for SN 2004gq above are from LOSS; position end figures by
R. Behrend (Geneva Observatory) from Manzini's image:  04s.87,
53".6.  Manzini adds that nothing is visible at this location on
Digitized Sky Survey images or on his earlier images (no dates
specified).  Additional magnitudes for SN 2004gq:  Dec. 4.38 UT,
