WZ Sge: superhump period Dear Colleagues, We have updated the superhump period of WZ Sge as 0.057194(15) d using new epochs of superhumps. As reported in the recent postings, recent superhump maxima have been highly affected by the overlapping eclipses. The period should be therefore treated as a preliminary one. We have also confirmed the trend of the increased fading rate. The observed increased fading rate in conjunction with the overlapping eclipses on superhumps seems to suggest a "beat phenomenon" as the possible origin of the fading (as observed in DV UMa and IY UMa). But this needs to be confirmed by the subsequent observations. Regards, Taichi Kato VSNET Collaboration team
