EG Cnc: short rebrightening?

     Geoff Stone, Nataly Katysheva, Sergey Shugarov, Osaka Kyoiku U. team,
Tonny Vanmunster, Itoh-san and Kyoto U. team have reported the observations.
The estimated superhump period after the previous rebrightening is 0.06033 (7) d.
The superhump period seems to become shorter and may reflect the shrinking disk.
The object was at 16.2 mag on Nov. 15.5 but at 15.7 mag on Nov. 15.7. This will be
not an ordinary rebrightening but a short rebrightening, which was observed also on
Oct. 28. The next rebrightening is expected to occur two days later.
