OT J184228.1+483742 : ordinary superhumps appeared at last!!!

 We have received further observations from Gianluca Masi and Enrique 
de Miguel. The reported data show, very interestingly, periodic 
variations like supehrumps with ~ 0.1 mag. With PDM analysis, 0.0743(5)
d is obtained as the superhump period.
 This is extremely long for WZ Sge type dwarf nova. Considering
also the long delay of development of ordinary superhumps, this
object may be a bouncer whose secondary is one of the most evolved.

 Further observations are strongly encouraged!
