SBS 1108+574: refined superhump period

> SBS 1108+574 large-amplitude variation?

   This phenomenon was most likely artificial, and the data by
I. Voloshina confirmed the presence of regular superhumps.
We have received further data from Viktor Malanushenko (APO) 
and Kiyota-san.  The refined superhump period is 0.039059(8) d
and Pdot = +2.6(0.9)*10^(-5).
Spectroscopic observation is still needed.
