V4641 Sgr observations from Kiyota-san Dear Colleagues, S. Kiyota-san (Tsukuba, Japan) has sent time-series observations of V4641 Sgr on July 11, 12 and 14. The light curves are not flat as in quiescence. Although there is little evidence of short-term flares, moderate variations seem to be present. More detailed analysis will be presented by Uemura-san.
