V4641 Sgr: activity on June 2 As reported by Kato-san, we again detected some fluctuations on June 2. We performed time-series observations at Ouda, and the light curve shows a 0.4mag-hump around June 2.66 UT. A few shorter-scale flares were superimposed on this large hump. We are now processing images taken on June 3. Results will be reported later. Regards, Makoto Uemura
