Neutral hydrogen (at λ = 21 cm) and carbon monoxide (at λ = 2.6 mm) line observations of the interstellar medium in the neighborhood of the association Ara OB1 are reported. The observed H I distribution indicates the presence of an expanding structure. The total H I mass associated with such feature amounts to 4800 solar masses, and its momentum and kinetic energy are ∼ 4×104 M☉ km/s and 3i×1048 erg, respectively. The H I structure, 42 pc in diameter, expands at a speed of 10 km/s. A possible origin for the expanding H I structure, and a genetic link between such structure and Ara OB1 are proposed.
