The spectacular ring nebula RCW58 around the Wolf-Rayet star WR40 (HD 96548, WN8) has been observed by the IRAS-Survey instrument and by the IRAS Chopped Photometric Channel (CPC) to study its IR flux and morphology. The survey data were examined with the Groningen Exportable Infra-red High-resolution Analysis system (GEISHA) software, and analysed in terms of line and dust contributions.
