ASASSN-15na: new SU UMa-type dwarf nova with double wave modulations

   Josch Hambsch has reported observations on three
nights.  The data show double wave modulations
(full amplitude 0.10 mag) with a period of 0.06304(5) d.
The profile does not resemble those of early superhumps
but two humps are almost alike.  There remains
a possibility of a half period; in this case,
the object may be an EI Psc-type object.
More observations are needed.
