OT_J191443.6+605214 (var/Dra): decrease of the superhump amplitude

   We have received further data from Maehara-san, Nakajima-san,
Pavol A. Dubovsky and Kyoto team (observer: Ohshima-san).
Recent data indicate that the amplitude of superhumps has diminished.
This behavior is frequently seen in SU UMa-type dwarf novae with
positive period derivatives, preceding the regrowth of superhumps
during the late stage (cf. http://adsabs.harvard.edu/abs/2003PASJ...55..989K).
Further observations are strongly encouraged to follow the complete
evolution of the superhumps.
