Abstract
The infrared cirrus are the filamentary emission seen at high galactic latitude in the IRAS data. This emission is associated with galactic interstellar clouds and was expected.
The average brightness at 100 µm is in rather good agreement with predictions based on classical interstellar dust models. Nevertheless the emission at shorter wavelengths is far in excess of the predictions of these models, and requires the presence of very small particles such as polycyclic aromatic molecules which are heated for short periods by single photons.
The structure and brightness of these cirrus clouds are such that they will be a limitation to the sensitivity of future space observatories in the far infrared.
