  We present the discovery of a new H I structure in the NGC 7194 group from
the observations using the Karl G. Jansky Very Large Array. NGC 7194 group is a
nearby (z ~ 0.027) small galaxy group with five quiescent members. The
observations reveal a 200 kpc-long H I plume that spans the entire group with a
total mass of M$_{HI}$ = 3.4 x 10$^{10}$ M$_{\odot}$. The line-of-sight
velocity of the H I gas gradually increases from south (7200 km s$^{-1}$) to
north (8200 km $^{-1}$), and the local velocity dispersion is up to 70 km
s$^{-1}$. The structure is not spatially coincident with any member galaxies
but it shows close associations with a number of blue star-forming knots.
Intragroup H I gas is not rare, but this particular structure is still one of
the unusual cases in the sense that it does not show any clear connection with
sizable galaxies in the group. We discuss the potential origins of this
large-scale H I gas in the NGC 7194 group and its relation with the
intergalactic star-forming knots. We propose that this HI feature could have
originated from tidal interactions among group members or the infall of a
late-type galaxy into the group. Alternatively, it might be leftover gas from
flyby intruders.
