Scientific paper

A spectral analysis of the fluctuations of the infrared sky radiance at 10 microns was made. The data are compared to literature. The consequences of the results on infrared observing for future large telescopes are discussed: the data suggest that in order to achieve background-noise-limited performance in the 10-micron atmospheric window chopping with frequencies of about 8 Hz and amplitudes of about 10 arcsec is mandatory.
