Infrared Observations of Comet 1965f
Abstract
Infrared photometric measurements of Comet 196Sf were made on 19 days during October and November, 1965. Absolute intensities as a function of the comet's distance to the Sun were measured in a region centered on the cometary nucleus at wavelengths near 1.65,2.2,3.4, and 10 . On three days the intensity in the tail was measured. Color temperatures were calculated in both the head and tail region from these absolute intensities. From the color temperatures the nature of the emissivity of the emitting particles is derived and the nature of some possible materials is discussed.
