EG Cnc: next rebrightening information

     Tamas Tordai, Geoff Stone, Osaka Kyoiku U. team, Nataly Katysheva,
Sergey Shugarov, Tonny Vanmunster, Ian Miller, Arto Oksanen and Kyoto
U. team have reported further observations.
     The object showed five rebrightenings with the constant interval of one week.
In the 1996 outburst, the 6th (last) rebrightening however occurred 10 days
after the 5th one. If this outburst has the same profile, the object will undergo the
next rebrightening 5 days later (Nov. 23). We should pay attention to the object
in order not to miss the rebrightening.
     The object has continued to show superhumps. The period in the present dip phase
is 0.06033(6) d and the amplitude is about 0.12 mag. The signal might become weaker.
Continuous observations are encouraged.
