A bizarre video from the Newsflare archive of a huge, multi-coloured cloud appearing in the sky in Escazu, Costa Rica.

The footage, shot by Jessie Montealegre in September 2015, shows the apocalyptic-looking sky in all its glory.

"Suddenly a massive amount of people stopped and stood still as they were astonished at how the skies opened up," Jessie said.

"It was a nice coincidence that the video was taken on Costa Rican's Independence Day."

The phenomenon is believed to be cloud iridescence.

Jessie Montealegre, from Fuquay-Varina, North Carolina and her husband, Jose were in Escazu, Costa Rica, when suddenly a massive amount of people stopped and stood still as they were astonished at how the skies opened up. "It was like something I've never seen before," said Jessie. For some it was like an act of God. It is a small glimpse of what heaven will truly be like. It makes you remember that God can come back at anytime. Jessie and Jose thought that it was a nice coincidence that the video was taken on Costa Rican's Independence Day.
