1. Introduction

NGC 205, one of the companions of M31, is classified as peculiar dE5. It shows a dozen bright early type stars and dark clouds, hence signatures of recent star formation (Hodge 1973). The HI emission is extended to about [FORMULA] (Young and Lo 1997). NGC 205 was also detected by IRAS at 12-100 µm with a spectral energy distribution steeply rising between 60 and 100 µm (Rice et al. 1988, Knapp et al. 1989) indicating the presence of cool dust at a temperature around 25 K and a slight extension at 60 and 100 µm along PA = [FORMULA]. NGC 205 is also the first among all ellipticals which was detected at the 1.1mm continuum (Fich and Hodge 1991).

Here new ISO observations between 120 and 200 µm are presented bridging the spectral energy distribution between IRAS and mm range and addressing the extension of the dust emission.
