Variations in the optical surface brightness of the night sky on angular scales of arcseconds to degrees are contributed to by phenomena ranging from geophysics to cosmology. Known time-independent (over years) sources include (1) fluctuations in the distant galaxy distribution and (2) scattered disk light off dust in the plane of our galaxy and at high latitudes (IRAS cirrus; Low et al. 1984). Sandage (1976) found optical “cirrus” on photographic plates, which were later correlated with bright 100 μm cirrus (de Vries and Le Poole 1985). We describe here a systematic investigation of fainter and more widespread high-latitude IRAS cirrus using deep multicolor charge-coupled device (CCD) imaging photometry (Guhathakurta and Tyson 1989).
