BELGIAN ASTRONOMICAL SOCIETY V.V.S. - Working Group Variable Stars Cataclysmic Variables Circular No.108 1996, September 16 Ed.: T. Vanmunster, Walhostraat 1A, 3401 Landen, BELGIUM Internet: tvanmuns@innet.be TEL. 32-11-831504 -------------------------------------------------------------- The CATACLYSMIC VARIABLES Home Page: http://www.cv.psi.edu =================================================================== PV Per [UG, 14.9p - 20:p] ========================= Eric Broens, Mol, Belgium reports his visual detection of an outburst of the CVAP object PV Per. Confirmation by CCD has been obtained from Tonny Vanmunster, CBA-Belgium Observatory, Belgium. 1996 Sep 14.026 UT, [14.9 (G. Poyner, 0.40-m refl.); Sep 15.924 UT, 14.8 (E. Broens, 0.35-m refl., seq: GSC); Sep 15.933 UT, 15.6 (T. Vanmunster, 0.25-m SCT+ST-7, unfilt.); PV Per is a little studied cataclysmic variable, which was last seen in outburst by M. Iida (Japan) on March 10, 1996 [Outburst Activity Database of Selected Cataclysmic Variables]. This was a faint outburst, observed by CCD only. V1363 Cyg [UGZ:, 13.0p - <17.6p] ================================ Gary Poyner, Birmingham, UK has detected a brightening of this interesting variable, which is part of the TA/BAAVSS Recurrent Objects Programme. His observation was confirmed by Tonny Vanmunster, CBA- Belgium Observatory, using a 25-cm SCT and CCD. Available observations : 1996 Sep 10.972 UT, [15.6 (G. Poyner, 0.40-m refl., seq: TA); Sep 12.896 UT, 15.9 (G. Poyner); Sep 12.942 UT, 15.9 (G. Poyner); Sep 12.972 UT, 16.5 (T. Vanmunster, 0.25-m SCT+ST-7, unfilt.); Sep 13.903 UT, [15.6 (G. Poyner); Sep 14.979 UT, 16.8 (T. Vanmunster & R. Fidrich, 0.25-m SCT+ ST-7 CCD, unfiltered exposure); The exact nature of V1363 Cyg is still unknown. Some sources [Downes & Shara] list it as an UGZ:-type dwarf nova, while others [Bruch & Schimpke, A&AS, 93, 419-439, June 1992] classify it as a possible VY Scl type variable, based on spectroscopic observations. Follow-up observations therefore are highly encouraged. Tonny Vanmunster
