Abstract
The results of 21 cm H line observations of the southern SNR G.261.9, plus 5.5 are reported, considering the problem of H I shells around SNRs. Two clouds that are probably related to the SNR were found, and the prominent H I features around it are discussed. The first cloud is an emission region with velocities between 22 and 46 km/s which shows the contours of brightness temperature remarkably distorted, resembling an explosive event. The gas appears approximately ring-shaped around the remnant, suggesting an expanding shell, and the calculated parameters are in good agreement with those derived for other SNRs. The other cloud is a high velocity emission region with velocities between 70 and 100 km/s, and there is a region of low density emission between these two features.
