BELGIAN ASTRONOMICAL SOCIETY V.V.S. - Working Group Variable Stars Cataclysmic Variables Circular No.57 1995, September 14 Ed.: T. Vanmunster, Walhostraat 1A, 3401 Landen, BELGIUM Internet: tvanmuns@innet.be TEL. 32-11-831504 P. Van Cauteren, de Borrekenslaan 54, 2630 Aartselaar, BELGIUM Internet: pvancaut@innet.be TEL. 32-3-8774098 =================================================================== FX Cep [UGSS?, 15.0p - 17.5p] ============================= Following the request on VSNET by Tonny Vanmunster, Landen, Belgium for confirmation of his outburst detection of FX Cep, we have been informed by Jochen Pietz, Erftstadts, Germany that he independently also observed the outburst. The available observations are as follows : 1995 Sep 11.891 UT, 14.9: (J. Pietz, 0.40-m refl.); Sep 12.847 UT, 14.9 (T. Vanmunster, 0.35-m refl., seq: GSC); This CVAP object was last seen in outburst on 1995, July 30, by Tonny Vanmunster, when it reached mag. 14.5 (CVC 49). We refer to CVC 51 for some interesting historical data about this dwarf nova, and for a discussion on its possible classification. Photometric summaries of the July/August 1995 outburst appeared in CVC 51 and CVC 52. IP Peg [UG, 12.0B - 16.6B] ========================== Further to the announcement in CVC 56 on a reported small brightening of IP Peg by B. Worraker, UK, we received following communication from Taichi Kato, Ouda Station, Kyoto University, Japan : "S. Takahashi (VSOLJ) has confirmed that observed times by Bill Worraker correspond to the expected orbital humps (phase 0.7-0.9). Takahashi also reports he observed IP Peg at mv=14.8 on Aug. 29.605, which also corresponds to the expected phase of an orbital hump. Therefore, we should check the orbital phases before interpreting 'bright estimates' of high-inclina- tion dwarf novae." A photometric summary of the current outburst is presented below. Eclipse timings intentionally have been left out of the table. ----------------------------------------------------------------------- DATE (UT) MAGN MS SEQ OBSERVER REMARKS SOURCE ----------------------------------------------------------------------- 1995 09 04.094 [15.0 mv TA Vanmunster, T. 35-cm refl.
