Wow what caused those brilliant colors and patterns and how long did that last, Wat?
Displays like these require a layer of clouds for the red light of sunset to be projected onto, but at the same time a clear sky just over the horizon so that the sun can hit those clouds from underneath.
The best part of the display lasted about 10 minutes, though some red was visible near the horizon for at least a half hour. Sunsets last longer the higher your latitude is.
