We report the discovery of a small bipolar Herbig-Haro
jet, HH 872, powered by the low-luminosity source
ESO-Hα 574 in Chamaeleon I. The end-to-end projected size
of the jet in [SII] images is only 3150 AU. Infrared images
marginally resolve the central source showing a structure
elongated perpendicularly to the jet axis, possibly a disk seen at
a large angle with respect to the plane of the sky. The brightest
feature of the jet, peaking at a distance of from the
central source, is likely to result from enhanced outflow activity
in the last decade.
Key words: stars: low-mass, brown dwarfs / stars: pre-main sequence / ISM: jets and outflows
