BELGIAN ASTRONOMICAL SOCIETY V.V.S. - Working Group Variable Stars Cataclysmic Variables Circular No.138 1997, May 11 Ed.: T. Vanmunster, Walhostraat 1A, 3401 Landen, BELGIUM Internet: tvanmuns@innet.be TEL. 32-11-831504 CBA Belgium Web Page : http://www.astro.columbia.edu/~cba/be =================================================================== The Complete CVAP Listing ========================= The following table lists all objects currently belonging to the Belgian Cataclysmic Variables Alert Programme (CVAP). Items marked with an (*) in the first column are new additions. The 'TYPE' column has been further updated for objects with a known subtype. Some individual comments on new additions : Tau 034525 : Large amplitude outbursts, lasting >= 1 day suggest dwarf nova nature. Likely not a flare star. GP Com : AM CVn star. No outbursts detected so far. Disk may be in a permanent cold state without outbursts. May show a superoutburst during the next few years [12]. Var21 CrB : Discovered by Antipin (IBVS 4343). Shows both short and long outbursts. Var43 Her : Discovered by Antipin (IBVS 4360). RY Ser : Largely neglected dwarf nova. Var25 Oph : Discovered by Antipin (IBVS 4344). Large amplitude. Lanning 17 : Nova-like object ? In need of dense monitoring. N Lac 1986 : Discovered by Honda in November 1986 as an 8 mag star (IAUC 4275). Discovery image seen on 2 simultaneous exposures. Existence of object not established. VARIABLE RA DECL TYPE MAG_RANGE REMARKS NAME [2000.0] MAX MIN DK Cas 00 18 08.39 +57 26 03.2 UGSS 15.3p 19.5:p [2,3] AS Psc 01 28 10. +31 14 57.
