(fwd) RXTE PCA X-ray light curves (Craig Markwardt) We have received the following report from the RXTE team: Greetings-- I have composed a web page with Jean Swank about the most recent RXTE PCA X-ray observations of V4641 Sgr. The source is indeed exhibiting large amplitude X-ray variations which are comparable in timescale to the optical modulations. This is much stronger variation than the source exhibited in June of 1999, whose light curve is also shown.
