[vsnet-alert 3843] DV UMa rapid fading




DV UMa rapid fading

The eclipsing SU UMa-type dwarf nova, DV UMa, which had been in 
superoutburst ([vsnet-alert 3791]), is now undergoing a rapid 
fading phase.  In the lightcurve on 20 Dec observed at Kyoto, 
the 0.3 mag fading for 6 hours and the decrease of superhump 
amplitude are clearly seen.  

Follow up observations are strongly encouraged to clarify 
the nature of this important phase.  

Regards,
Makoto Uemura and Taichi Kato
