Geometrical configurations of the disk of Venus during the six TEXES observing runs of 2012−2016. The terminator is indicated by a black line and the subsolar point is shown in black. Two of the runs (January 2012, March 2015) correspond to the evening terminator (night side to the left of the terminator), while the four others correspond to the morning terminator (night side to the right of the terminator). These two geometrical configurations lead to different thermal structures at high latitudes.
