Abstract

We report observations of diffuse far‐infrared emission from interstellar dust at high Galactic latitudes using a rocket‐borne, liquid‐helium cooled telescope and photometer. The photometer has 5 spectral bands ranging from 90 μm to 190 μm with 0.5°∼0.65°FWHM fields‐of‐view. The detectors, stressed and unstressed Ge:Ga photoconductors, were cooled to 1 K and coupled to charge integrating amplifiers to achieve high sensitivity. We observed regions near Ursa Major including infrared cirrus, high latitude molecular clouds, and the HI hole, a region of uniquely low neutral hydrogen column density. Preliminary analysis shows a strong correlation of the emission at 134, 154, and 186 μm with 100 μm IRAS data.
