XM116HT = TCP J14225968+4122545: WZ Sge-type star with prominent early superhumps Tamas Tordai has reported observations. The object shows double-wave 0.3-mag early superhumps. The period is still somewhat uncertain (0.0557-0.0571 d). Bright WZ Sge stars with large-amplitude early superhumps are rare and observations are encouraged.
