SBS 1108+574 large-amplitude variation?

   Crimean Astrophys. Obs. team (A. Baklanov and O. Antonyuk,
relayed by E. Pavlenko) reported further observations.
The state of the object has apparently changed.  Now it shows
large (up to 0.4 mag) variations and the maxima do not
follow the previous periodicity.  The waveform looks rather
irregular, and the strongest period is around 0.047 d.
This change is unexpected and requires independent confirmation!
