EG Cnc: superhump continues

     Nataly Katysheva, Sergey Shugarov, Pavol A. Dubovsky, Tonny Vanmunster
and Osaka Kyoiku U. team have reported the observations.
     The object is at V=17.5, which is 1.3 mag brighter than in quiescence. The
object continues to show late-stage superhumps with a period of 0.06041(3) d.
The superhump profile is double peaked and seems gradually to change, namely
the positions of the double peaks change.
     The primary target must be ASASSN-18aan and the daily observation of EG Cnc
is not needed. However, time-series observation of EG Cnc will be also interesting.
The color has been red (V-Ic = +0.9) yet.
