ASASSN-16da: new WZ Sge-type dwarf nova with early superhumps

   Tonny Vanmunster has reported observations.
The object shows double-wave modulations (total
amplitude 0.10 mag) with a period of 0.0562(2) d.
It is somewhat a pity that the object was detected
much earlier, but remained unrecognized for three
nights.
