Confirmation and further follow-up observation are urgently needed. Mike Simonsen: This new cataclysmic variable in Psc looks like a WZ Sge-type. This one is bright and should be interesting to follow for quite some time if it is like most WZ Sge types, with the possibility of echo outbursts on the tail end of the event. Ian Miller has reported observations. As expected, the object clearly exhibits a typical WZ Sge-type with early superhumps having unequal double maxima. The mean full amplitude was 0.11 mag. The best period of early superhumps is 0.0571(2) d, qualifying the object as being a short-period WZ Sge-type object.
