[vsnet-alert 607] superhumps of EG Cnc

[Katsura Matsumoto <katsura@quasar.cc.osaka-kyoiku.ac.jp>]

   We obtained a continuous (four hours) CCD V-band light curve of EG Cnc 
last night. The observed light curve shows superhumps with a low 
amplitude, approximately between 0.03 and 0.04 magnitude.
A preliminary analysis yielded a period of 0.058 day, which is one of the 
shortest known among dwarf novae.

   The long interval of outbursts and the large amplitude support the 
WZ Sge-type classification of EG Cnc; the observed doubly-humped feature
of superhumps strongly suggests that the object was observed in the earlier
stage of a superoutburst. Further follow-up observations are encourged.
