V4641 Sgr: rebrightening! We are now having a run on V4641 Sgr at Ouda and found that the object is brighter at Rc=12.6mag. It is not clear whether this brightening is a temporary 1-mag hump or sign of a new giant outburst, but it is certain that the object entered a new active phase! This brightening trend has been also reported by R. Stubbings in [vsnet-obs 40119]. Regards, Makoto Uemura
