V4641 Sgr run on May 25 (Roland Santallo) Dear Colleagues, Roland Santallo (Southern Stars Observatory, Tahiti) just sent us a run on May 25, covering the phase preceding the Kyoto/Ouda observation. Santallo's observation indicates steadily increasing activity, which very likely smoothly evolved into the violent state later on May 25. Further analysis will be reported by Uemura-san. Regards, Taichi Kato VSNET Collaboration team
