Re the pink rainbow:
BBC Weather presenter Simon King said there was no specific name for the phenomenon, which was caused by a regular rainbow and a pink sunset happening at the same time.
"We've got a regular rainbow, which is caused by water droplets in the atmosphere reflecting the sunlight into the spectrum of different colours," he said.
"The other thing is a pinkish sunset caused by sunlight having to pass through a lot more atmosphere - due to the low sun angle late in the day - hence the shortwave colours - violets, blues, greens - are diminished and we only see the pinks and reds, giving the rainbow a pinkish colour."
