SUPERNOVA 2001hg IN NGC 4162
     T. Puckett, Mountain Town, GA; and A. Sehgal, Woodinville, WA,
report the discovery of an apparent supernova (mag 17.4) on an
unfiltered CCD frame taken with the Puckett Observatory 0.60-m
automated supernova patrol telescope on Dec. 4.44 UT.  SN 2001hg is
located at R.A. = 12h11m53s.18, Decl. = +24o06'49".4 (equinox
2000.0), which is 9".4 east and 35".3 south of the center of NGC
4162.  The new object was confirmed on CCD frames taken on Dec.
5.29, but it is not present on images taken by Puckett on Mar. 12,
Apr. 9, and 26 (limiting mag about 20.5) or on Palomar Sky Survey
images taken on 1996 May 14 (limiting mag about 21.0), 1994 Jan. 15
(limiting mag about 21.0), and 1950 June 10 (limiting mag about
20.0).


SUPERNOVA 2001hh IN MCG -02-57-22
     M. Schwartz, Cottage Grove, OR, and W. D. Li, University of
California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report
the discovery of an apparent supernova (mag about 17.5) on
unfiltered images taken with the 0.5-m Tenagra III automated
telescope on Dec. 4.1 and 5.1 UT.  The new object is located at
R.A. = 22h36m30s.40, Decl. = -12o34'08".0 (equinox 2000.0), which
is 11".1 east and 7".1 south of the nucleus of MCG -02-57-22.  A
KAIT image taken on Nov. 2.1 showed nothing at this position
(limiting mag about 19.0).
