     R. Arbour, South Wonston, Hampshire, England, reports his
discovery of an apparent supernova (mag 16.3) on an unfiltered CCD
image taken on Dec. 17.952 UT using a 0.3-m f/6.3 reflector.  SN
2002jy is located at R.A. = 1h21m16s.27, Decl. = +40o29'55".3
(equinox 2000.0), which is 46".4 west and 37".6 north of the center
of the galaxy NGC 477.  Nothing is present at this location on a
1995 blue Palomar Sky Survey plate (Digital Sky Survey).  Further
images taken by Arbour on Dec. 18.713 and 18.719 show the new
object at about the same brightness, and an unfiltered CCD image
taken by T. Boles, Coddenham, Suffolk, England, on Dec. 18.731
yields mag 16.5 and position end figures 16s.23, 55".6.  T.
Vanmunster, Landen, Belgium, reports his independent discovery of
SN 2002jy (providing position end figures 16s.26, 55".5) on
unfiltered CCD images taken on Dec. 18.96 with a 0.35-m f/6.3
telescope during an automated supernova-search program; a
confirming CCD image was obtained on Dec. 18.991 by P. Van
Cauteren and P. Lampens at Beersel, Belgium, yielding V = 16.0 for
the new object.  SN 2002jy was not visible on Vanmunster's CCD
image taken on Oct. 11.075 (limiting unfiltered mag 17.2) or on
1977 red Digitized Sky Survey images (limiting mag 19.5).

S/2002 J 1
     Further to IAUCs 7555 and 7900, S. S. Sheppard reports the
discovery of another satellite of Jupiter with the 2.2-m reflector
at Mauna Kea.  The astrometry is given on MPEC 2002-Y22, along
with orbital elements by B. G. Marsden showing this to be another
retrograde satellite (i = 163 deg, P = 748.5 days, H = 15.7).

     R. J. Ivison, Royal Observatory, Edinburgh; and T. B. Lowe,
James Clerk Maxwell Telescope, report flux densities for V4743 Sgr
at various wavelengths with SCUBA, RxA3, and RxB3 detectors
(0.45-1.4 mm) and with the Very Large Array (3.6 cm; uncertainties
</= 25 percent in flux):  Oct. 11.9 UT, VLA, < 0.12 mJy; 12.2,
0.45 mm, 369 +/- 63; 12.2, 0.85 mm, 100 +/- 10; 27.0, VLA, 0.20;
27.3, 0.85 mm, 177 +/- 22; Nov. 6.2, 1.3 mm, 115 +/- 23; 15.0, VLA,
1.21; 15.1, 0.9 mm, 276 +/- 79; 15.1, 1.4 mm, 199 +/- 57.  The
VLA source is located at R.A. = 19h01m09s.32, Decl. = -22o00'06".1
(equinox 2000.0; uncertainties </= 0".5).
