Cataclysmic Variables Circular No.2

 

BELGIAN ASTRONOMICAL SOCIETY V.V.S. -  Working Group Variable StarsCataclysmic Variables Circular No.2                     1994, May 5Ed.: P. Van Cauteren, de Borrekenslaan 54, 2630 Aartselaar, BELGIUM     73064.1123@compuserve.COM                    Tel. 32-3-8774098     T. Vanmunster, Walhostraat 1A, 3401 Landen, BELGIUM     Internet: tvm@lms.be                         Tel. 32-11-831504=================================================================== VVS BELGIUM - CATACLYSMIC VARIABLES ALERT PROGRAMME We would like to invite colleagues to participate in our Cataclysmic Variables Alert Programme.Professional astronomers have asked us to monitor several possiblerecurrent objects in order to confirm the identification and/or theCV-subclass. We have divided the objects in two groups:  GROUP 1========For these objects, our observations of an outburst could secure the correct identification and confirm the CV classification.  EV Aqr   UGZ:V1289 Aql   NL:AQ CMi   UG:V337 Cyg  UG:IR Lyr   UG:V650 Ori   UG:AS Psc   UG 1963V701 Tau   UG:SS LMi   N or UG 1980  GROUP 2========For these objects, our observations could confirm the subclass. FS Aur   UGZ:   ug secure, only Z Cam subclass uncertainCI Gem   UGSU:   ug secure, only SU UMa subclass uncertainV358 Lyr   N:/UGWZ 1965  The above objects are not included in The Astronomer RecurrentObjects programme, but we feel they also need our attention. Indeed,most professional astronomers will only be interested to observe suchobjects if it is proven that they are indeed peculiar and the identification is somewhat secured.Charts and finder charts for the variables in our CV Alert Programme can be obtained from the editors.We are interested to receive your observations of outbursts of thesestars.  Paul Van Cauteren
