We present a spectroscopic study of the long-recurrence-time
dwarf nova V 592 Herculis based on observations obtained during
its August 1998 superoutburst. From the analysis of the radial
velocities of the Hα emission line we find a most likely
orbital period of 
min, but the 
min
alias cannot be completely discarded. Both periods imply a
very small period excess
and supports the brown-dwarf like nature of the secondary star.
