A comparison of red spots in the atmosphere of Jupiter
Abstract
Comparative broadband relative photometry has been obtained for the Great Red Spot, a well-developed Little Red Spot at 19.°2 planetographic or 16.°9 planetocentric latitude, and selected belts and zones. These results reveal the presence of a UV absorber in both the GRS and the LRS that is not present in the belts. Mapping of the latitudinal dimensions obtained from measurements of ground-based photographs onto the latitudinal dependence of zonal winds derived from the Voyager data indicates that the position of the LRS and GRS relative to the zonal winds is similar and suggest that the LRS is an anticyclonic system. Questions raised by this analysis are presented for further investigation.
