For those interested in the present V4641 Sgr outburst. Despite poor weather conditions the reported observations hereby attached indicate obvious turbulent behaviour. Follow-up measurements were performed during the night 21-22 May 2002. They are presently being processed. Weather conditions were much better but V4641 Sgr might have returned to a calmer state. We'll see! Regards, Berto Monard Bronberg Observatory
