SDSS J141118.31+481257.6: superhump continues and will show another rebrightening

     Tonny Vanmunster and Crimean Astrophys. Obs. team (N. Pit and E. Pavlenko) have
reported further observations. The object was 17.1 mag on July 4th, which is 2.6 mag
brighter than its quiescence. We can see superhumps with the most likely period of 0.0321 d.
Thus the object has been active yet and will show another rebrightening.
     In order to detect the next rebrightening and establish the superhump period, further
observations are encouraged. Most of the people observe ASASSN-18ey (=MAXI J1820),
so snapshots are also very welcomed.
