Previous scans with PHT C200 revealed that the elliptical dwarf galaxy N205 is
spatially resolved in the FIR and that the SED rises steeply between 150 and
205micron indicating a large amount of very cold dust about 8-10K (Fig.1).
This result, however, relies essentially on the 205micron data and may be
influenced by the uncertain background determination. The scans did not cover
sufficient background around N205, because they were designed for M31 (Fig.2).
Therefore we need more observations to verify this unique very cold dust
discovery with ISO.
