crepuscular rays (photo by Stuart Gallaway)
In this photograph a number of wide bands of blue can be seen with several narrow bands
between them. (photo by K.B. Shone, UK)
One sometimes observes dark bluish streaks which radiate from the sun across the purple light. These streaks are the shadows of clouds at or below the horizon; becoming visible at the antisolar point (anticrepuscular rays)
Note

- The name "crepuscular rays" is also used, though not universally, to denote shadowed bands cast by clouds on a layer of haze at any time of the day.
