Incredible video footage has captured the moment an amazing rainbow cloud suddenly appeared in the sky.
The multi-coloured light, which appears like a hole in the middle of the sky, was caught on camera in Fazenda São João, a tourist hotspot in Parana, Brazil.
Salesman André Luiz Nassif caught the moment on camera during a break from work on Sunday, January 28.
The phenomenon is actually known as irisation and occurs and is defined as multiple mixed iridescent colours caused by sunlight being diffracted in clouds .
Meteorologist Graziella Goncalves told UOL : "It occurs due to the decomposition of sunlight in the seven colours of the rainbow."

The definition of irisation is the dispersion of the incidence of sunlight in the ice crystals of the cloud or of particles in the atmosphere.
He added: "There is a dispersion of sunlight in the atmosphere, that at some times of the day the the angle between the sun and the horizon is less than 10%, so that the sun's light shows such colors, which are usually almost random layers or bands at the edges of the cloud."

These types of cloud usually occur very close to the sun, making them extremely difficult to capture on camera.
According to Nassif, the cloud was visible for around half an hour.
And it seem to catch the attention of many people nearby, with one restaurant reporting customers getting up in the middle of their meal to get a glimpse of the strange cloud.
