NGC 2359, a H II region located at a distance of 5 kpc from the Sun (e.g., Goudis et al. 1994), appears as a ring like nebula surrounding HD 56925, a Wolf-Rayet star of type WN4. The nebula consists of a filamentary shell, a southern bar and streamers of diffuse gas (cf. Schneps et al. 1981, SHWB). Here we report the results of H I 21-cm line and radio continuum observations in the direction of NGC 2359.
