Abstract
Hubble Space,Telescope ultraviolet images of Saturn obtained with the Faint Object Camera near 220 nanometers reveal a dark oval encircling the north magnetic pole of the planet. The opacity has an equivalent w idth of similar to 11 degrees in latitude and is centered around simil ar to 79 degrees N. The oval shape of the dark structure and its coinc idence with the aurora detected by the Voyager Ultraviolet Spectromete r suggest that the aerosol formation is related to the auroral activit y.
