V4641 Sgr inactive again? Dear Colleagues, We have just started analyzing the Kyoto June 5 observation (observer R. Ishioka). The dramatic variation recorded on June 4 seems to have disappeared (a look at the earliest segment of the data). Further analysis on the complete data sets will be later presented by Uemura-san. Since the variabity of this source is extremely unpredictable, further detailed, long time-series observations are absolutely needed. Regards, Taichi Kato VSNET Collaboration team
