Chris Taylor sent us this picture of an upside down rainbow over Stapleford in Nottinghamshire!
In more scientific language, it's called a 'circumzenithal arc', or 'Bravias' arc', and it appeared for around 40 minutes at around 7.20pm last night.
They usually just last for a couple of moments and are caused by light shining at a specific angle through tiny ice crystals in the clouds.They are much brighter than a normal rainbow with the colours in reverse order.
