BELGIAN ASTRONOMICAL SOCIETY V.V.S. - Working Group Variable Stars Cataclysmic Variables Circular No.1 1994, May 3 Ed.: P. Van Cauteren, de Borrekenslaan 54, 2630 Aartselaar, BELGIUM 73064.1123@compuserve.COM TEL. 32-3-8774098 T. Vanmunster, Walhostraat 1A, 3401 Landen, BELGIUM Internet: tvm@lms.be TEL. 32-11-831504 =================================================================== From the Editors: Welcome to the first issue of the Cataclysmic Variables Circular. The objective of this free electronic circular is to provide first hand information on cataclysmic variables activity (e.g., outbursts of important dwarf novae, overview tables of magnitude estimates for recent outbursts, important nova activity, chart information, and so on). This publication will be restricted to cataclysmic variables monitored by Belgian observers, and thus is complementary to circulars from the AAVSO, The Astronomer and other organizations. We will continue issuing our weekly reports, containing observations of all type of cataclysmic stars. DM LYRAE [UG, 13.6p - 18p] ========================== Paul Van Cauteren, Aartselaar, Belgium has detected an outburst of this dwarf nova type cataclysmic variable. Confirmation has followed from Tonny Vanmunster, Landen, Belgium 1994 May 01.017 UT, 14.8 (P. Van Cauteren, 0.40-m refl); May 01.915 UT, 14.6 (T. Vanmunster, 0.35-m refl); May 02.896 UT, 15.0 (T. Vanmunster) Previous outbursts of this UG star: 1993 Dec 09, 13.7 (D. York, USA) 1992 Sep 29, 13.5 (Unconfirmed outburst, The Astronomer, UK) 1992 Jul 23, 14.0: (B. Worraker, Didcot, UK) IR LYRAE [UG:, 14.6p - 16.0p] ============================= Summary of preliminary observational results, obtained for this interesting possibly dwarf nova type variable. 1994 Apr 19.132 UT, <14.7 (T. Vanmunster, 0.35-m refl); Apr 28.941 UT, 14.3: (T. Vanmunster); Apr 28.974 UT, 14.0 (P. Van Cauteren, 0.40-m refl); Apr 30.920 UT, 14.0 (T. Vanmunster); Apr 30.995 UT, 13.8 (G.
