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 :
