SUPERNOVA 2003gw IN UGC 3252
On August 7, Mark Armstrong, Rolvenden, reported during searches
for the UK Nova/Supernova Patrol, his detection of a possible
supernova on a single image of UGC 3252 obtained on 2003 August
7.11406UT at:
RA 05h 11m 47.70s DEC +67o 29' 22.2"  Mag 17.1 Offsets 14"E, 6"N.

Confirmation was obtained by Mark on 2003 August 07.94474UT which
gave end figures of RA 47s.68, DEC 22".2. Due to deteriorating
conditions, the galaxy was imaged at only 31 degrees altitude but
exposed for 5 minutes instead of the usual one minute giving images
as good as those of the discovery frame. 

The object was not recorded on Mark's images of 2000 Nov 3 and 2003
Mar 22 to a limit of magnitude 19.0 and also was not seen on
Palomar Sky Survey red and blue plates.

The object has been designated supernova 2003gw on IAUC 8176.

Congratulations to Mark on his 43rd supernova discovery.

COMET P/2003 O3 (LINEAR)
Peter Birtwhistle, Great Shefford, reports via IAUC 8174 that he
has imaged an apparent asteroid of magnitude 18.9 reported by
LINEAR on July 30 and found it to be cometary. On July 31.10UT
using a 0.30-m reflector, a very faint tail of 10 arc seconds in
approximately PA 270-280deg was recorded. The coma diameter was
also found to be about 5 arc seconds in diameter on Aug 2.08UT.

SUPERNOVA 2003gt IN NGC 6930
A LOTOSS discovery has been reported on IAUC 8172 of a supernova of
magnitude 16.4 recorded on 2003 July 29.4UT in NGC 6930. The
position is:
RA 20h 32m 59s.12 DEC +9 52' 19".3 (2000), 4.9"E and 4.7"S the host
galaxy's nucleus.

SUPERNOVA 2003gv IN MCG +05-3-66
A further LOTOSS discovery of an apparent supernova of magnitude
18.4 recorded on August 6.5UT has been reported on IAUC 8175. The
position of the new object, in MCG +05-3-66, is:
RA 01h 08m 53.18s DEC +32 05' 59.3" (2000), 11.1"E and 0.3"S of the
host galaxy's nucleus.

SUPERNOVA 2003gu IN UGC 12231
Further to the report on TA E-Circular 1903 of the detection of
this object by Mark Armstrong, A. V. Filippenko et. al., University
of California, Berkeley, give details on IAUC 8175 of a spectrum
suggesting it is of type II, shortly after maximum.
