ASASSN-17la: likely early superhumps (new WZ Sge-type dwarf nova)

   Tonny Vanmunster has reported observations on two
nights.  The data apparently show early superhumps
(0.03 mag) with a period of 0.06050(6) d.
Although the existence of the variation looks secure,
more observations are definitely needed since this
period is long for a WZ Sge-type dwarf nova
It may be another candidate for an object with
multiple rebrightenings.  If it is the case, it would
be highly desirable to follow the object continuously
to measure the period of stage A superhumps.
