Re: V4641 Sgr: rebrightening!
The light curve on June 4 taken at Ouda shows a large
(amplitude=1.2mag) hump and many 0.2mag-small flares.
The large hump has a peak at about June 4.65UT and a duration of ~3 hr.
The small flares looks have a weak, but characteristic
periodicity (50-100s).
After the object experienced the hump, it returned at quiescent
level. Follow-up observations are encouraged since amplitudes
of modulations seem to become larger with time.
