1999 RZ_253
Astronomers at the Space Telescope Science Institute have reported
on IAUC 8143 that the Hubble Space Telescope recorded a binary
companion to the transneptunian object 1999 RZ-253 on Apr 23. The
object was then 41.55AU from the earth and the measured separation
is equivalent to 6300 +/- 600 km in the plane of the sky.

SUPERNOVA 2003em In ESO 478-G6
Berto Monard, Pretoria, South Africa, has reported his discovery of
a possible supernova of magnitude R=17.2 on CCD images of 2003 May
27.158UT and located at:
RA 02h 09m 20.23s DEC -23 24' 53.0" (2000), 32"E and 2"N of the
centre of the presumed host galaxy ESO 478-G6. An earlier image by
Monard secured on 2003 Mar 10.7 did not show the object.

SUPERNOVAE 2003en, 2003eq-2003eu
The above designations of six supernovae reported by the Hubble
Higher-z supernova team all relate to objects of magnitude 23 or
fainter. Further details appear on IAUC 8140.

SUPERNOVA 2003eo IN ANONYMOUS GALAXY
W. M. Wood-Vasey has reported a possible supernova of mag 20.2 on
NEAT images of Mar 27.14UT and located at:
RA 11h 03m 09.19s DEC -05 46' 09.4" (2000), 1.5"W and 0.5"S of the
host galaxy according to IAUC 8140.

SUPERNOVA 2003ep IN NGC 7053
M. Papenkova has reported on IAUC 8140 a possible supernova of
magnitude 15.7 first recorded on LOTOSS/KAIT images May 17.5UT at:
RA 21h 21m 07.34s DEC +23 05' 05.8" (2000), 3.9"W of the centre of
NGC 7053.  

SUPERNOVA 2003ev IN ANONYMOUS GALAXY
Papenkova also reports on the same IAUC that a possible supernova
of magnitude 18.5 has been recorded on 2003 June 1.3UT at:
RA 13h 10m 31.80s DEC -21 39' 49.6" (2000), 2.2"E and 6.4"N of the
centre of an anonymous galaxy.

SUPERNOVA 2003ew
This designation was given to another Hubble Higher-z object of
magnitude 24.1 according to IAUC 8141.

SUPERNOVA 2003ex IN ANONYMOUS GALAXY
Wood-Vasey also reports a magnitude 19.1 supernova at:
RA 13h 27m 32.31s DEC +5 31' 14.4" (2000) 2.5"W and 1.1"S of the
nucleus of the host galaxy. It was initially recorded Mar 26.44UT.

SUPERNOVA 2003ey IN ANONYMOUS GALAXY
Wood-Vasey reports another supernova, mag 19.2 at:
RA 14h 20m 03.28s DEC -08 28' 40.0" (2000) 2.4"W and 0.8"S of the
host first recorded May 24.33UT according to IAUC 8141.

SUPERNOVA 2003ez IN PGC 42782
Papenkova also reports a possible supernova recorded June 3.2UT at:
RA 12h 43m 11.87s DEC -02 30' 04.1" (2000). The magnitude 17.5
object is 4.5"W and 0.7"S of the centre of the galaxy PGC 42782.
