VLT optical observations of V821 Ara(=GX339-4) in an extended ``off'' state
We report on low-resolution spectroscopy of GX339-4 during its current, extended X-ray ``off'' state in May 2000 (r=20.1) obtained with the VLT Focal Reducer/low dispersion Spectrograph (FORS1). Although we do not positively detect the secondary star in GX339-4 we place an upper limit of 30 percent on the contribution of a ``normal'' K-type
