SUPERNOVAE 2004gw AND 2004gx
     Further to IAUC 8435, T. Puckett and R. Ireland report the
discovery of an apparent supernova (mag 17.9) on an unfiltered CCD
frame taken with the 0.60-m automated supernova patrol telescope on
2004 Dec. 27.14 UT (and confirmed on frames taken on Dec. 29.11 at
mag 17.7).   SN 2004gw is located at R.A. = 5h08m48s.41, Decl.
= +62o26'20".7 (equinox 2000.0), which is 17".7 east and 14".2
south of the center of PGC 16812.  The object is not present on
images taken by Puckett on Sept. 10 and Nov. 9 (limiting mag about
     D. Rich, Hampden, ME, reports his discovery of an apparent
supernova (mag about 17.6) on unfiltered CCD frames taken with a
0.31-m reflector on 2004 Dec. 30.96 and 2005 Jan. 1.93 UT.  SN
2004gx is located at R.A. = 23h33m30s.80, Decl. = +24o01'07".0
(equinox 2000.0), which is about 7".0 west and 5".4 south of the
center of UGC 12663.  Nothing is visible at this location on
Palomar Sky Survey plates (limiting red mag 20.1, limiting blue mag
19.7) or on CCD frame taken by Rich on 2004 Oct. 21.01 and Nov.
20.07 (limiting mag about 18.6).
