(Anomalous?) Outburst of SS Cyg


(vsnet-alert)

Dear Colleagues,

Recent observations seem to indicate that the dwarf nova SS Cyg may be on the rise to an anomalous outburst (at last?). Close observations tonight are needed to see if there follows a rapid or slow rise, which helps in dis- criminating the outburst type. The VSNET Home Page displays the present light curve.

Regards,
Taichi Kato

Original request for monitoring an anomalous outburst of SS Cyg:

> (vsnet 389, A. Hempelmann 1995 Dec. 12) 
> 
> Dear Colleagues, 
> 
> I would like to remember that Constanze la Dous and myself are waiting for
> an anourmalous outburst of SS Cygni to observe this CV with the IUE during
> rise time. In the last two months I continously received your observations
> of SS Cyg so that at each time we had a clear picture of the SS Cyg status.
> Many thanks for you very helpful support of our work! 
>
> However, my present feeling is that your special interest in this star has
> a little bit decreased, because the number of observations of this star I
> received has been dramatically decreased in the last two weeks. So I would
> like to ask everybody to focus his or her attention to this star so long as
> we need your monitoring observations. And this can be a long time...
> Many thanks for your kind support. 
>
> Merry Christmas, and a happy new year, 
> 
> Alexander Hempelmann
