ASASSN-17bl: new likely WZ Sge-type dwarf nova

   Josch Hambsch has reported observations.
The object started to show superhumps on Feb. 4.
The current period is 0.0560 d or 0.0545 d
(aliases).  The period may be that of stage A
ones or mixed value with stage B.
Since the object was already in outburst on
Jan. 24, the long waiting time (11 d) of
superhumps strongly suggests a WZ Sge-type object.
Further detailed observations are urged.
