KV And [UGSU, 14.6p - 22.5p]
============================
Tonny Vanmunster, Landen, Belgium reports an outburst detection of
the cataclysmic variable KV And. Confirmation has come from Gary
Poyner, Birmingham, UK and Eric Broens, Mol, Belgium. Available
observations :
1995 02 17.802 UT, [14.5 (T. Vanmunster, 0.35-m refl., seq: GSC);
02 21.885 UT, 14.7 (T. Vanmunster, 0.35-m refl., seq: GSC);
02 21.890 UT, 14.8: (G. Poyner, 0.40-m refl.);
02 21.894 UT, 14.8 (E. Broens, 0.35-m refl., seq: GSC);
KV And was last reported in outburst on December 28, 1994, by John
Bortle, USA, when it reached mag. 14.4.
UNCONFIRMED OUTBURST OBSERVATIONS
=================================
Two outburst observations of interesting dwarf novae recently have
been reported by Laszlo Szentasko, Veresegyhaz, Hungary. Bad weather
has prevented other observers from confirming these observations.
It concerns :
V1113 Cyg [UGSU, 14p - <17p]
1995 01 31.722 UT, 14.0 (L. Szentasko, 0.33-m refl.);
The previous outburst of V1113 Cyg was independently detected by
L. Szentasko and T. Vanmunster on 1994, September 1. It reached mag 13.0
at maximum brightness. During that outburst, Taichi Kato and his team
members at Ouda Observatory, Japan, detected superhumps in V1113 Cyg,
using V-band CCD photometry.
DM Lyr [UG, 13.6p - 18p]
1995 02 01.188 UT, 14.2 (L. Szentasko, 0.33-m refl.);
DM Lyr was last seen in outburst on 1994, November 1 by Gary Poyner,
Birmingham, UK, at mag. 14.5 (TA-sequence).
FS Aur [UGZ:, 14.4v - 16.2v]
============================
A faint outburst of this cataclysmic variable has been observed by
Tonny Vanmunster, Landen, Belgium and confirmed by Eric Broens, Mol,
Belgium. FS Aur is on the Belgian Cataclysmic Variables Alert Programme
(CVAP).
1995 01 23.872 UT, [15.0 (T. Vanmunster, 0.35-m refl., seq: GSC);
01 26.917 UT, 15.2 (T. Vanmunster);
01 26.935 UT, 14.9: (E. Broens, 0.35-m refl., seq: GSC);
01 30.773 UT, 15.0: (E.Broens);
According to our records, the object was last seen in outburst on
1994 Dec 13 (Indiana Univ. Roboscope), when it was at magnitude 14.8.
The star can become as bright as mag 13.4pg.
EF Peg [UGSU, 10.7p - [17p]
===========================
Final observations, completing the photometric summary of EF Peg published
in CVC No.26, are listed below.
