ASASSN-16jb: new WZ Sge-type dwarf nova

   Berto Monard and Josch Hambsch have reported observations.
The object shows double-wave modulations (full amplitude
0.04 mag) with a period of 0.0634(1) d.
The period may suggest a period bouncer.
Intensive observations (particularly to determine
the periods of early superhumps and stage A superhumps)
are urgently requested, since it would provide
an excellent opportunity to determine the mass ratio
in a period bouncer.
