SBS1108+574 variable superhump period

   We have received further data from Colin Littlefield,
Enrique de Miguel, Osaka Kyoiku U. team and Viktora Malanushenko
who observed at Apache Point Observatory (APO, relayed by
E. Pavlenko).  The data now show clear signature of period variation.
Pdot = +19(6)*10^(-5), and the period should not be the orbital one.
Continued observations are strongly encouraged!
