Smoothed SOFIA Images of Comet ISON
Date: 24 Oct 2013

Images of comet ISON were obtained by SOFIA's FORCAST camera at wavelengths of 11.1, 19.7 and 31.5 microns. Measurements at 31.5 microns, crucial for determining the temperature and other characteristics of the comet's material, cannot be made using ground-based telescopes.
