Nova Vulpeculae 1984 No. 2
Abstract
A. R. Taylor, Kapteyn Astronomical Institute; E. R. Seaquist, University of Toronto; and S. R. Pottasch, Kapteyn Astronomical Institute, report the radio detection of Nova Vul 1984 No. 2 with the Very Large Array. Multi-frequency observations show a steeply rising spectrum with the flux density at longer wavelengths increasing with time. Measured flux densities (in mJy) at 5 GHz were: 1985 July 16, 4.1; Oct. 7, 7.0; Dec. 18, 11.0. A high- resolution map at 15 GHz on Oct. 7 revealed a main radio source plus a lobe of emission extending ~ 0"25 to the southeast. There is no counterpart of the lobe to the northwest of the main component. Radio coordinates of the nova are R.A. = 20h24m40s52, Decl. = +27deg40'48"1 (equinox 1950.0).
