V4641 Sgr observation on July 16 (Kiyota-san) Dear Colleagues, S. Kiyota-san (Tsukuba, Japan) reported a time-series observation of V4641 Sgr on July 16. Although the object was rather inactive, there seem to be occassional ~0.1 mag modulations with a time-scale of minutes to tens of minutes. More detailed analysis, together with the data obtained at Kyoto (Ishioka-san), Ouda (Uemura-san), and by Torii-san, will be undertaken by Uemura-san. Regards, Taichi Kato VSNET Collaboration team
