  FU Orionis-type objects (FUors) are young low-mass stars undergoing powerful
accretion outbursts. The increased accretion is often accompanied by collimated
jets and energetic, large-scale molecular outflows. The extra heating during
the outburst may also induce detectable geometrical, chemical, and
mineralogical changes in the circumstellar material, affecting possible planet
formation around these objects. V346 Nor is a southern FUor with peculiar
spectral characteristics. Decades after the beginning of its outburst, it
unexpectedly underwent a fading event around 2010 due to a decrease in the mass
accretion rate onto the star by at least two orders of magnitude. Here we
present optical and near-infrared photometry and spectroscopy obtained after
the minimum. Our light curves show a gradual re-brightening of V346 Nor, with
its Ks-band brightness only 1.5 mag below the outburst brightness level. Our
VLT/XSHOOTER spectroscopic observations display several strong forbidden
emission lines towards the source from various metals and molecular hydrogen,
suggesting the launch of a new jet. Our N-band spectrum obtained with VLT/VISIR
outlines a deeper silicate absorption feature than before, indicating that the
geometry of the circumstellar medium has changed in the post-outburst period
compared to peak brightness.
