NOVA VULPECULAE 1984 No. 2
     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).


NOVA SCORPII 1985
     R. Lukas, Wilhelm Foerster Sternwarte, has identified images
on IIa-O plates taken with the GPO astrograph at the European
Southern Observatory as follows: 1981 July 23, mag 16; Aug. 7, 17;
1985 Aug. 11, 16; Aug. 17, 17.5.
