Over the last number of years spectroscopic studies have strongly supported the assertion that protostellar accretion and outflow activity persists to the lowest masses. Indeed, previous to this work the existence of three brown dwarf (BD) outflows had been confirmed by us. In this paper we present the results of our latest investigation of BD outflow activity and report on the discovery of two new outflows. Observations to date have concentrated on studying the forbidden emission line (FEL) regions of young BDs and in all cases data has been collected using the UV-Visual Echelle Spectrometer (UVES) on the ESO VLT. Offsets in the FEL regions are recovered using spectro-astrometry. Here ISO-Oph 32 is shown to drive a blue-shifted outflow with a radial velocity of 10-20 kms−1 and spectro-astrometric analysis constrains the position angle of this outflow to 240 ◦ ± 7◦. The BD candidate ISO-ChaI 217 is found to have a bipolar outflow bright in several key forbidden lines (VRAD =-20 kms −1, +40kms−1) and with a PA of 190◦-210◦. A striking feature of the ISO-ChaI 217 outflow is the strong 1Based on data collected by UVES observations (079.C-0375(A)) at the VLT on Cerro Paranal (Chile) which is operated by the European Southern Observatory (ESO)
