Variable XM78HT belongs to WZ Sge type, since: Amplitude of superoutburst is highter than 5 magnitudes; The superhumps with period of about 0.05472d were detected and their period changes and color indices changes are typical for WZ Sge type; Right away after the superoutburst the early superhumps occurred with the period close to ½ superhumps’ one; Period excess value is about epsilon=0.033; Pdot=3.5*10^(-5). The deep darkening (more than 2.5 magnitude) was detected during the slow brightness decrease after superoutburst. Al of these properties are typical for WZ Sge type dwarf novae.
