We have extended our study of sulphur monoxide towards other less opaque cirrus cores and have clearly detected 3 out of 6 sources observed, for the Draco cloud, LVC127+20, and MBM 32. We find for at least one further cloud (MBM 32) that SO is extended. Assuming that the lines are optically thin we derive column densities of about N (SO)= 5 1012 cm−2. Based… (More)
