VARIABLE STAR NEAR UGC 10700
     Further to IAUC 8147, J. Graham and W. Li report the LOTOSS
discovery, on unfiltered KAIT images taken on June 17.4 and 18.4
UT, of a variable star (mag about 16.5) located at R.A. =
17h06m06s.12, Decl. = +25o51'53".3 (equinox 2000.0), which is 51".5
east and 79".9 south of the nucleus of UGC 10700.  A KAIT image
taken on June 11.4 showed nothing at this position (limiting mag
about 19.5).


SUPERNOVA 2003ed IN NGC 5303A
     C. J. Stockdale, Naval Research Laboratory (NRL); R. A. Sramek,
National Radio Astronomy Observatory; S. D. Van Dyk, Infrared
Processing and Analysis Center, California Institute of Technology;
K. W. Weiler, NRL; and N. Panagia, European Space Agency and Space
Telescope Science Institute, report the detection of radio emission
from the type-II supernova 2003ed (IAUC 8129) with the Very Large
Array.  On June 17.12 UT in 'A' configuration, radio-flux densities
of 1.81 +/- 0.33 mJy at 22.46 GHz (wavelength 1.3 cm), 2.35 +/-
0.26 mJy at 14.94 GHz (2.0 cm), 1.77 +/- 0.11 mJy at 8.46 GHz (3.5
cm), and 0.65 +/- 0.07 mJy at 4.86 GHz (6.2 cm) were measured at
R.A. = 13h47m45s.39, Decl. = +38o18'21".0 (equinox 2000.0; +/- 0".2
in each coordinate).  This is in close agreement with the reported
optical position (end figures 45s.36, 20".3; IAUC 8129).  The radio
emission is apparently still optically thick at 4.86 and 8.46 GHz
and slightly more radio luminous in all bands, at a comparable age,
than was SN 1993J (to which SN 2003ed has been compared; cf. IAUC
8144).  Radio monitoring is continuing.


COMET P/2003 L1 (SCOTTI)
     Clearly diffuse NEAT images of this comet, taken with the
Palomar 1.2-m Schmidt telescope on three nights in 2002 April, were
identified and measured by M. Meyer.  Additional astrometry and the
following orbital elements (MPEC 2003-M21) confirm the suspicion
(cf. IAUC 8145) that this is a short-period comet.

                    Epoch = 2003 Mar. 22.0 TT
