V4641 Sgr optically rather inactive

   Imamura-san (Okayama U. of Sci. team) has reported time-resolved
photometry of V4641 Sgr on Aug. 12.  There were no strong short-term
variation, confirming the relatively calm optical state reported by
Rod Stubbings.  Spectroscopic observations to detect emission lines
would be desired.
