WZ Sge superhump period Dear Colleagues, > We have more closely examined these original data. The cycle counts > in Bohusz and Udalski 1979 have been found to be correct (to the present > knowledge of the new superhump period), while there seem to be ambiguities > in superhump identifications in Patterson et al. 1981. We have securely > identified three superhump timings on Dec. 22-25, and probable one on > Dec. 28. Three possible superhump timings on Dec. 19 and 26 do not match > the currently determined period, and the ephemeris by Bohusz and Udalski > 1979. It is very likely the period of 0.05714 d was strongly affected > by these "noisy" identifications. Using new secure identifications of > superhump times, from Bohusz and Udalski 1979 and Patterson et al. 1981, > we obtained a refined superhump period of 0.05722 d for the 1978 > superoutburst. This superhump period is 1.0% longer than the orbital > period. This would indicate that WZ Sge has the perfectly same fractional superhump excess as in AL Com!
