2003IAUC.8153....2S

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.
