Considerable change is apparent between these and observations in 1994-1997 : in particular the North-South asymmetry at visible wavelengths has reversed, with the southern hemisphere brighter, as during the Voyager epoch. The asymmetry shows considerable variation with wavelength in the near-infrared : in the 889nm methane band… CONTINUE READING
