BELGIAN ASTRONOMICAL SOCIETY V.V.S. - Working Group Variable Stars Cataclysmic Variables Circular No.167 1998, August 04 Ed.: T. Vanmunster, Walhostraat 1A, 3401 Landen, BELGIUM Internet: Tonny.Vanmunster@advalvas.be TEL. 32-11-831504 CVC Web Page : http://www.cba.phys.columbia.edu/cvc =================================================================== New cataclysmic variable in Draco ================================= We have been informed by Michael Schwartz, Cottage Grove, OR about his discovery of a new cataclysmic variable in Draco : "I am 'responsible' for finding supernova 1998di in an anonymous galaxy (see IAUC 6982, that was issued on August 3rd). However, spectral observations now reveal that this is not a supernova, but a galactic dwarf nova in outburst, projected near a distant anonymous galaxy". Michael Schwartz kindly has sent us full details about the related spectrographic analysis by Jha, Garnavich, Challis and Kirshner (Center for Astrophysics), that likely will appear in an IAUC tomorrow. The spectrum of the new dwarf nova resembles that of the helium dwarf nova CR Boo near maximum (Patterson et al., 1997, PASP, 109, 1100). The new object is located at RA = 19h24m38s.19, Decl = +59o41'46".7 (equinox 2000.0), which is about 0".6 east and 3".8 north of the nucleus of an anonymous galaxy. A picture of the new object is available at the following URL : http://www2.netcom.com/~pfactors/tenagra.html Some photometric observations : 1998 Jul 22.46 UT, [19 (M. Schwartz, unfiltered CCD image); Aug 02.48 UT, 16.8 (M. Schwartz, unfiltered CCD image); We strongly recommend CCD observers to photometrically monitor this object. Tonny Vanmunster
