  We report lunar occultation (LO) and speckle interferometry observations of
Haro 6-37, all carried out at lambda=2.2 microns. The main finding is the
discovery of a new close companion by LO, subsequently confirmed by speckle.
The two techniques yield values in excellent agreement, with 0.331 arcseconds
and 181 degrees for the separation and position angle respectively.
Additionally, the LO data show evidence of what might be interpreted as
scattered light from the inner part of the dust disk which is known to exist
around Haro 6-37 from mm-radio observations (Osterloh & Beckwith 1995). However
this last conclusion is subject to some uncertainty because of possible
contamination of the signal during data acquisition. LO and speckle results are
in good agreement also for what concerns the brightness ratio of the newly
found companion to the main component, R=0.10 or Delta K=2.5. We discuss the
possible implications on the general picture of Haro 6-37, in particular for
what concerns the ages of the components and the dust disk.
