Si IV and N V in HD 150168
Caption: Animated GIF demonstrating ioniation changes in the wind of
the B supergiant HD 150168. Direct comparisons are meaningful for
velocities more negative than about -400 km/s. At velocities more positive
than this, comparisons are complicated by the presence of the red component
of the N V doublet.
