WX Cet: start of rapid fading? We have just started this evening's CCD observations of the super- outbursting WX Cet. From the quick-look image, WX Cet seems to have been entering its rapid declining stage from the superoutburst. WX Cet showed a rather peculiar fading pattern during this stage in I-band, as extracted from my article in IBVS 4256: > Another peculiar feature of WX Cet can be found during its terminal > decline from a superoutburst. In contrast to most SU UMa-type dwarf > novae, the rate of decline slowed down far before reaching quiescence. > [Averaged decline rates of 0.80 mag day$^{-1}$ and 0.41 mag day$^{-1}$ > were obtained for the intervals of July 20 -- 22 and 22 -- 23, > respectively. Note that WX Cet was at Ic=15.5 on July 23, which was > $\sim$ 2.0 -- 2.5 mag brighter than quiescence.] Similar phenomenon > was also observed in CT Hya (Nogami et al. 1995).

Observations are strongly urged during this important stage of the important superoutburst. Regards, Taichi Kato
