SUPERNOVA 2002au IN UGC 5100
     Independent discovery reports of an apparent supernova in UGC
5100 have been received from T. Puckett and A. Langoussis, Mountain
Town, GA, on images taken with the Puckett Observatory 0.60-m
automated supernova patrol telescope; and from W. D. Li, University
of California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), on
images taken the Katzman Automatic Imaging Telescope (KAIT).
Puckett provides the following position for SN 2002au:  R.A. =
9h34m37s.60, Decl. = +5 50'15".7 (equinox 2000.0), which is 16".0
west and 13".6 south of the center of UGC 5100.  Li provides
position end figures 37s.54, 15".7.  Unfiltered CCD magnitude
estimates, except photographic magnitudes for the Palomar Sky
Survey (PSS):  1951 Jan. 4 UT, [20.0: (PSS, via Puckett); 1992 Dec.
21 and 1998 Dec. 12, [21.0: (PSS, via Puckett); 2000 Mar. 9, [20.5:
(Puckett); 2002 Jan. 18.4, [19.0: (Li); Feb. 1.3, hint of presence
(Li); 8.3, 17.7: (Li); 9.22 and 10.14, 18.0 (Puckett); 10.3, 17.3:
(Li).


SUPERNOVA 2002av IN ESO 489-G007
     M. Schwartz, Cottage Grove, OR; and W. D. Li, University of
California at Berkeley, on behalf of LOTOSS, report the discovery
of another apparent supernova (mag about 17.7) on unfiltered images
taken with the 0.5-m Tenagra III automated telescope on Feb. 8.2
and 9.2 UT.  The new object is located at R.A. = 6h08m06s.34, Decl.
= -23o59'13".2 (equinox 2000.0), which is 10".8 east and 17".7
north of the nucleus of ESO 489-G007.  A KAIT image taken on Feb.
1.2 already showed a hint of the new object, while an image taken
on Jan. 23.2 showed nothing at this position (limiting mag about
18.5).


SUPERNOVA 2002as IN UGC 3418
     S. Jha, T. Matheson, P. Challis, and R. Kirshner, Harvard-
Smithsonian Center for Astrophysics, report that a spectrum (range
370-750 nm) of SN 2002as (cf. IAUC 7819), obtained by L. Macri on
Feb. 9.13 UT with the F. L. Whipple Observatory 1.5-m telescope (+
FAST spectrograph), shows it to be a type-II supernova near maximum
light.  The spectrum exhibits a blue continuum with broad P-Cyg
Balmer lines.  Adopting the NASA/IPAC Extragalactic Database
recession velocity for UGC 3418 (6743 km/s) yields an expansion
velocity of 8700 km/s for the supernova, measured to the minimum of
the H_beta profile.
