V1251 Cyg [UG:, 12.5p - [15p]
=============================

Gary Poyner, Birmingham, UK has asked us for confirmation of his
outburst detection of this very interesting dwarf nova type cata-
clysmic variable. Tonny Vanmunster, Landen, Belgium and Eric Broens,
Mol, Belgium have been able to confirm the observation. Details are 
as follows :

1994 Dec 30.7   UT, 12.9 (G. Poyner, 0.40-m refl., seq.: TA);
     Dec 30.785 UT, 13.7 (T. Vanmunster, 0.35-m refl., seq.: AAVSO);
     Dec 30.819 UT, 13.6 (T. Vanmunster, 0.35-m refl., seq.: AAVSO);
     Dec 30.951 UT, 13.2 (E. Broens, 0.35-m refl., seq.: TA);

All observations were made under very unfavorable conditions (stormy
weather).

Tonny Vanmunster remarks that there is a contradiction between the
star's position on the AAVSO chart (Dec 1990) and the image that appears
in [1]. Apparently, the position as indicated on the AAVSO chart seems
to be correct. Astrometric observations are urgently required to 
determine the precise position.

The star was last seen in outburst on October 27, 1991 (Moriyama and
Schmeer). According to our records, it reached mag. 12.5 at that 
occasion [2]. Kato [3] afterwards reported on the development of 
superhumps in V1251 Cyg. Apart from this, very little is known about 
the variable.
