Tourist films a solar halo above a waterfall at a cave in São Paulo state
Tourist and mountaineer Giba Morais filmed a solar halo above a waterfall at Casa de Pedra cave in Iporanga, in São Paulo state.
Morais was visiting the cave with four friends on an expedition to see its large entrance, which is in the Petar area.
A solar halo is a large circle around the Sun that can appear under certain conditions.
The sky was cloudy, but openings in the clouds let sunlight through as water fell from a crack near the cave entrance.
Morais said he saw two rainbow-like rings and described the view as magical and magnificent.
The video captured a rare natural sight at the cave, but no further plans or developments were given.

I have been mountaineering for more than 7 years already, here in the Curitiba region.
