CY UMa [UGSU, 11.9v - 17.0v]
============================
Patrick Schmeer, Bischmisheim, Germany and Tonny Vanmunster, Landen,
Belgium independently report an outburst observation of CY UMa.
Eric Broens, Mol, Belgium has confirmed the event. Observations are
as follows :
1995 05 19.868 UT, [13.5 (P. Schmeer, 0.20-m SCT);
05 19.931 UT, [14.7 (T. Vanmunster, 0.35-m refl., seq: AAVSO);
05 20.950 UT, 13.6 (P. Schmeer, 0.20-m SCT);
05 20.951 UT, 14.1 (T. Vanmunster, 0.35-m refl., seq: AAVSO);
05 20.974 UT, 13.8 (E. Broens, 0.35-m refl., seq: AAVSO);
It's interesting to note that the previous outburst of this dwarf nova
was observed as recently as March 18, 1995 (detected by Lasse Jensen,
Denmark). It's only the second time in the history of this dwarf nova
that two successive outbursts are separated by only 2 months. The first
case was in 1989 (separation 66 days), as recorded in our "Outburst
Activity Database on Selected Cataclysmic Variables (*)".
(*) This database shortly will become available on Internet, as part of a
paper to be published jointly by Steve Howell, Astrophysics Group,
Planetary Science Institute and the undersigned.
AK Cnc [13p - <17p]
===================
Laszlo Szentasko, Veresegyhaz, Hungary reports an outburst of this
dwarf nova, which is on the "Recurrent Objects Programme" of The
Astronomer Group, UK. No confirmative observations have been received
yet. The previous outburst of AK Cnc was reported on March 8th, 1995
by L. Szentasko and B. Worraker, Didcot, UK.
Available observations :
1995 05 03.840 UT, 14.0 (L. Szentasko, 0.33-cm refl.);
05 05.824 UT, 15.4 (L. Szentasko);
V795 Cyg [UGSS, 13.4p - <17.9:p]
