SUPERNOVA 1995K IN ANONYMOUS GALAXY
The High-Z Supernovae Search Team [B. Schmidt, Mount Stromlo
and Siding Spring Observatories; M. Phillips, M. Hamuy, R. Aviles,
N. Suntzeff, and R. Schommer, Cerro Tololo Interamerican
Observatory (CTIO); B. Leibundgut and J. Spyromilio, European
Southern Observatory (ESO); B. Kirshner, A. Riess, P. Challis, and
P.Garnavich, Harvard-Smithsonian Center for Astrophysics; and C.
Stubbs and C. Hogan, University of Washington] report the discovery
of a high-redshift supernova located 0".73 west and 0".82 north of
a galaxy at R.A. =10h50m47s.00, Decl. = -9o15'07".4 (equinox
2000.0); SN 1995K is offset 11".4 east and 31".6 north from a
nearby star (GSC 5499.0261; R.A. = 10h50m46s.2, Decl. = -9o15'39").
SN 1995K was discovered (at mag R about 22.5) on a frame taken with
the CTIO 4-m telescope on Mar. 30.1 UT and is mariginally detected
on a frame taken in poor conditions on Mar. 25.  The supernova is
not present on a deep image obtained on Mar. 7.  Spectra obtained
at the ESO New Technology Telescope on Apr. 3 suggest that the
object is a type-Ia event slightly past maximum.  The redshift of
the host galaxy, derived from narrow H-alpha + [N II] emission, is
z = 0.478.

COMET C/1994 G1 (TAKAMIZAWA-LEVY)
J. V. Scotti, Lunar and Planetary Laboratory, reports that
observations with the 0.9-m Spacewatch telescope on Apr. 5 and 6
show a secondary nucleus of comet C/1994 G1 = 1994f, 2 mag fainter
than the primary and separated by 6".9 in p.a. 70 deg.  No
companion was noted in the previous Spacewatch images, obtained on
Jan. 3.  Z.Sekanina, Jet Propulsion Laboratory, finds that the
observations are consistent with splitting on 1994 Sept. 4
(+/- 15), 105 days after perihelion, the companion's deceleration
being 21.8 (+/- 6.8) x 10^{-5 solar attraction.  Ephemeris:
1995 Apr. 23, separation 7".2 in p.a. 68 deg;
May 13, 7".3 in 67 deg; June 2, 7".2 in 65 deg.
During the Spacewatch January observation the separation would
have been only 1".1.

COMET D/1931 R1
MPC 24933 contains observations and MPC 25030 elliptical orbital
elements of a mag 15 comet discovered by C. W. Tombaugh on
exposures with the 0.3-m photographic telescope at the Lowell
Observatory in Sept. 1931.  As with C/1931 AN [cf. MPC 24423 and
24544; previously announced by Lampland and Newman (1933, A.N. 249,
105) as a minor planet], information about D/1931 R1 became
available in the late 1980s as the result of precise measurements
by B. A. Skiff following D. H. Levy's examination of the Lowell
Observatory plate archive.
