SUPERNOVA 2003gx IN MCG +06-3-7
     Further to IAUC 8108, T. Boles reports the discovery of an
apparent supernova on unfiltered CCD images taken on Aug. 3.038
(mag 18.6), 4.044 (mag 18.5), and 6.104 UT (limiting mag 20.5).
The new object is located at R.A. = 1h02m55s.09, Decl. =
+37o40'10".3, which is approximately 2".3 west and 13".0 south of
the center of MCG +06-3-7.  SN 2003gx is not present on Boles'
images from Jan. 16, 23, and Feb. 19 (limiting mag 19.0), and it is
not present on Palomar Sky Survey plates from 1989 (blue) and 1991
(red; limiting mag about 20.5).


SUPERNOVAE 2003gy, 2003gz, 2003ha, 2003hb
     Further to IAUC 8147, P. Astier and C. Pritchet, on behalf of
the CFHT Legacy Survey Supernova Project (plus D. Fouchez and J.
Raux), report the discovery of additional apparent supernovae found
on CCD images taken during the engineering pre-survey.  Additional
i' magnitudes:  2003gy, June 6, [24.5: (S/N = 5 for 2" aperture);
26.3, 23.8; 30.3, 23.7; July 4.3, 23.6.  2003gz, June 6, [24.5:;
26.3, 22.8; 30.3, 23.0; July 4.3, 23.0.  2003ha, June 5, [24.5:;
26.5, 22.0; 30.5, 21.5, July 4.5, 21.2.  2003hb, June 5, [24.5:;
26.5, 21.6; 30.5, 21.8, July 4.5, 21.9.

COMETS C/2003 H5, C/2003 H6, C/2003 H7 (SOHO)
     Further to IAUC 8138, D. Hammer has reported astrometric
measurements for several additional comets found on C2 coronagraph
images at the SOHO website by R. Kracht.  The reduced astrometry
and orbital elements by B. G. Marsden appear on MPEC 2003-P02.
C/2003 H6 and C/2003 H7 are obviously related to each other; C/2003
H5 belongs to the Meyer group.
