SUPERNOVA 1998en IN UGC 3645
W. D. Li, M. Modjaz, E. Halderson, T. Shefler, J. Y. King, M.
Papenkova, R. R. Treffers, and A. V. Filippenko, University of
California at Berkeley, report the discovery of an apparent
supernova in the course of the Lick Observatory Supernova Search
with the 0.8-m Katzman Automatic Imaging Telescope (KAIT).  SN
1998en was discovered on unfiltered frames taken on Oct. 30.5 (mag
about 18.4) and 31.5 UT (mag about 18.2).  The new object is
located at R.A. = 7h04m00s.05, Decl. = +50o40'30".0 (2000), which
is about 10".4 west and 18".3 south of the nucleus of UGC 3645.

SUPERNOVAE 1998eo, 1998ep, 1998eq
G. Aldering, Lawrence Berkeley National Laboratory, on behalf
of the Supernova Cosmology Project, reports the discovery of three
type-Ia supernovae, all found as part of their high-redshift
supernova search on the Keck II telescope:

SN      1998 UT     R.A.  (2000)  Decl.     I     z     Offset
1998eo  Oct. 15   4 56 15.47  - 3 46 38.7  23.6  0.84  34" W, 24" S
1998ep  Oct. 15  23 19 57.67  +16 03 19.5  20.1  0.11  near center
1998eq  Oct. 15  23 20 27.47  +15 55 43.7  24.8  1.20  near center

The supernova spectra were obtained at the Keck II telescope on
Oct. 27.  The redshifts were determined from host-galaxy emission
and absorption lines.  Both SN 1998eo and SN 1998eq are within 1"
of the host-galaxy centre.

SUPERNOVA 1998er IN GH 9-2
A. Becker, University of Washington, on behalf of the MACHO
Collaboration, reports the discovery of an apparent supernova,
possibly before maximum brightness, in the LMC background galaxy GH
9-2:  "The object is question was initally announced as an on-going
microlensing event (MACHO Alert 98-LMC-4) on an object located at
R.A. = 5h50m16s.87, Decl. = -71o14'13".5 (equinox 2000.0).
Inspection of the images shows that this object is superimposed on
the outer visible edge of the background galaxy GH 9-2, identified
in Gurwell and Hodge (1990, PASP 102, 849), and is therefore likely
a supernova.  The morphology of GH 9-2 suggests that this is a
late-type SBb galaxy, and SN 1998er is located 10".5 west and 4".8
north of the galaxy nucleus.  Images confirming this object's
brightening were taken with the Cerro Tololo 0.9-m telescope on
Nov.3.346 and 4.342 UT.  As of Nov. 4.491, the object was at
magnitudes R = 17.4 and V = 18.6.
