Fig. 1From: Mean winds at the cloud top of Venus obtained from two-wavelength UV imaging by Akatsukia 365-nm and b 283-nm radiance obtained with UVI at 17:29 and 17:26 UTC, respectively, December 7, 2015 (W m−2 sr−1 μm−1). Green dots indicate the ellipse obtained by limb fitting to refine navigation, and yellow dots demark the mapped limb corresponding to 70 km above the mean surface. Black dotted lines indicate longitude and latitudeBack to article page
