Abstract
The far-IR ISOPHOT maps of the spiral galaxies M51 and M101 at 60, 100, and at 175μm are analysed. For all areas in these galaxies the spectral energy distributions can be fitted with a single-temperature emission curve. Colours and dust temperatures were estimated for interesting sub-fields. The temperatures vary between 33K for HII regions, and 28K for the disk, arm and interarm regimes.
