Summer sun halo in Brazil

In late February, the temperature in Florianopolis in Brazil topped 32 degrees Celsius, which is usually for warm summer days in the region. However, when Cristiano Andujar looked up from the steps of the Cathedral, he saw clear signs of freezing air. "Around the sun were two beautiful ice halo, — he said. — People on the sidewalk stopped and showed them the finger."

In the photo you did Andujar, a large ring around the sun — a common 22-degree halo, which is created by sunlight shining through hexagonal ice crystals in Cirrus clouds. Floating at an altitude of nearly 10 km clouds freeze, despite the heat on the streets of Florianopolis.

Right under the 22-degree halo camera Andujar captured a very colorful band of light called rounded-horizontal arc, which creates ice crystals in the clouds. Summer is a season of education rounded-horizontal arcs, as they only appear when the sun is high in the sky — more than 58 degrees above the horizon. The huge size of the arc and a pure spectral color make the phenomenon one of the most beautiful ice halo.
