BELGIAN ASTRONOMICAL SOCIETY V.V.S. - Working Group Variable Stars Cataclysmic Variables Circular No.119 1996, December 28 Ed.: T. Vanmunster, Walhostraat 1A, 3401 Landen, BELGIUM Internet: tvanmuns@innet.be TEL. 32-11-831504 =================================================================== EG Cnc [UGSU, 11.9v - 17:v] =========================== Unfiltered CCD photometry by Tonny Vanmunster at the CBA Observatory, Belgium shows that EG Cnc is now having a second major post-outburst rebrightening. The event has been confirmed visually by Gary Poyner, Birmingham. Here are the observations : 1996 Dec 28.974 UT, 13.6 (T. Vanmunster, 0.25-m SCT, unfilt. CCD); Dec 28.969 UT, 13.6 (G. Poyner, 0.40-m refl., seq: VSNET); We are now (Dec 29.0 UT) performing time-series CCD photometry on this object, which we hope to continue till about Dec 29.3 UT. It will be extremely interesting to find out if superhumps are again appearing and, if so, to determine the associated superhump period in this stage. Remark that UZ Boo also showed a second post-outburst brightening during its August 1994 outburst [CVC 16]. Other recent observations of EG Cnc are summarized in the table below and complement the reports in previous CVC circulars. ------------------------------------------- DATE (UT) MAGN MS OBSERVER ------------------------------------------- 1996 12 21.142 16.06 CV Zissell 1996 12 21.950 13.6 mv Poyner 1996 12 22.199 13.5 CV Zissell 1996 12 22.773 14.10 CV Ouda 1996 12 22.821 14.17 CV Ouda 1996 12 22.91 13.6 mv Kinnunen 1996 12 22.963 14.1 mv Poyner 1996 12 23.067 14.1 mv Poyner 1996 12 23.558 15.15 CV Ouda 1996 12 23.851 14.9 mv Itoh 1996 12 23.855 15.68 CV Ouda 1996 12 24.563 16.16 CV Ouda 1996 12 24.611 [15.6 mv Koshiro 1996 12 24.864 15.77 CV Ouda 1996 12 25.17 [15.1 mv Kinnunen 1996 12 25.011 15.7 CU Vanmunster 1996 12 25.595 15.20 CV Ouda 1996 12 25.90 13.8? mv Kinnunen 1996 12 25.958 [15.9 CU Vanmunster 1996 12 25.987 [15.9 CU Vanmunster 1996 12 26.611 [15.6 CV Koshiro 1996 12 26.827 16.02 CV Ouda 1996 12 27.747 16.04 CV Ouda 1996 12 28.04 [15.9 CU Vanmunster Tonny Vanmunster
