Zonal wind map in Saturn’s stratosphere retrieved around 0.5–1 mbar on January 14 and 22, 2012, from ALMA CO (J=2–1) observations. The wind speeds have been corrected for line-of-sight projection effects. The planet rotation axis is displayed with a dashed black line, and isolatitudes are indicated by gray contours. The background image of Saturn was captured by amateur astronomer F. Willems on January 14, 2012, and was obtained from the PVOL database (http://pvol2.ehu.eus/).
