SUPERNOVA 2003gx IN MCG +06-3-7
On 2003 August 4 Tom Boles, Coddenham, England, e-mailed us to
report that he had discovered an apparent supernova on unfiltered
CCD images taken on 2003 Aug. 03.038UT (mag 18.6) and 04.0435UT
(mag 18.5) with a 0.35-m reflector in the course of the U.K.
Nova/Supernova Patrol.

The new object is located at RA 01h 02m 55.09s DEC +37 40' 10.3"
(2000) which is approximately 2.3"W and 13.0"S of the centre of the
galaxy, MCG +06-3-7. The suspect is not present on Boles' images
from 2003 Feb. 19 (limiting mag 19.0), nor on those of Jan 16 and
23. It is also not present on Palomar Sky Survey II, red plates
(1991.757) and blue plates (1989.683).

Given the faintness of the new object against the limiting
magnitude of the exposures, the Central Bureau initially deferred
announcement until further results were obtained.

The new object was again recorded by Tom on Aug. 6.104UT and with
stacking of images, the limiting magnitude was estimated to be
20.5.

On this basis the object was designated supernova 2003gx and
details announced on IAU Circular 8178.

Congratulations to Tom on the discovery of his 45th supernova.

SUPERNOVAE 2003gy, 2003gz, 2003ha, 2003hb
The above designations have been assigned on IAUC 8178 to
discoveries made by the CFHT Legacy Survey Supernova Project during
the engineering pre-survey phase. The objects were all recorded on
June 22 and are of magnitude 21 or fainter.

SATELLITES OF (22) KALLIOPE and (45) EUGENIA
The Committee on Small Bodies Nomenclature (CSBN) agreed at its
recent meeting in Sydney that the name 'Linus' should be adopted
for the satellite of the asteroid (22) Kalliope. 

The Working Group on Planetary System Nomenclature (WGPSN) who
formerly had responsibility for the naming of satellites of
asteroids, previously also assigned the name 'Petit Prince' to the
satellite of (45) Eugenia according to IAUC 8177. This same group
has also announced a lengthy list of names and designations for
satellites of major planets, which will be published in 'The
Astronomer'.
