The Belt of Venus or Venus's Girdle is the Victorian-era name for an atmospheric phenomenon seen at sunrise and sunset. Shortly after sunset or shortly before sunrise, the observer is, or is very nearly, surrounded by a pinkish glow or antitwilight arch that extends roughly 10°–20° above the horizon. Often, the glow is separated from the horizon by a dark layer, the Earth's shadow or "dark segment". The Arch's light rose (pink) color is due to backscattering of reddened light from the rising or setting Sun

Some shots I took last year.
This is looking to the east.
Thanks for the explanation Jeanette and a series of lovely photos depicting the phenomenon. The last shot of the Moon and cloud column is quite dramatic!
A lot of people miss this due to being opp the sun set or rise, ahwell, I find it just as interesting, sometimes you can see a tall mountain casting a peaking shadow into the pink :
