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.
