Van Cauteren, de Borrekenslaan 54, 2630 Aartselaar, BELGIUM Internet: pvancaut@innet.be TEL. 32-3-8774098 =================================================================== IP Peg [UG, 12.0B - 16.6B] ========================== Tonny Vanmunster, Landen, Belgium has detected an outburst of this eclipsing dwarf nova. An independent outburst observation has also been received from Jochen Pietz, Germany. 1995 06 08.994 UT, [12.9 (T. Vanmunster, 0.35-m refl., low, seq: TA); 06 19.014 UT, 13.0 (T. Vanmunster); 06 19.029 UT, 13.8 (J. Pietz, 0.20-m SCT); 06 19.965 UT, 13.7 (T. Vanmunster); 06 20.007 UT, 13.9 (T. Vanmunster); IP Peg was last seen in outburst on December 5th, 1994, by Bill Worraker, Didcot, UK [CVC 22]. Bill is heading an international observing project on IP Peg (a TA/BAAVSS initiative), to study the eclipse behaviour of this dwarf nova. Observers are strongly encouraged to send their eclipse timings (with full details on sequence and comparison stars) to Bill Worraker (bill.worraker@aea.orgn.uk). BZ UMa [UGSU:, 10.5v - 17.8v] ============================= The BZ UMa outburst, announced in CVC 41, very likely was a normal outburst, given the short duration of the event. Only few observations are available, as one can derive from the photometric summary below : ----------------------------------------------------------------------- DATE (UT) MAGN MS SEQ OBSERVER REMARKS SOURCE ------------------------------------------------------------------------ 1995 06 09.941 [13.7 mv TA Poyner, G. 40-cm refl.
