V4641 Sgr new light curve! Dear Colleagues, We have put on the VSNET webpage a new light curve drawn from the June 4 observation by Uemura-san. The amplitude of the variation surpassed that on May 24. You can see the activity the object showed only half a day ago! http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Xray/v4641sgr02.html Regards, Taichi Kato VSNET Collaboration team
