Three unidentified objects seen hovering over Leshan City, Sichuan Province.

At dusk about 8 pm, three "suns" suddenly appeared and illuminated the sky above Leshan City, Sichuan Province, lasting for about 10 minutes on July 26, Sichuan News reported.

"This remains a mystery and needs a comprehensive analysis," said Professor Wang Sichao, a researcher of the Purple Mountain Observatory of the Chinese Academy of Sciences.

The "suns" attracted plenty of attention. According to photographer Lu Shan, the objects first appeared in the west. After about ten minutes, the objects moved northward and their diameter gradually narrowed.

"As they faded, they were moving like the sunset, and the light was quite gentle," Lu said.

Some people talked of a UFO invasion, but Lu, after conducting some informal research, believes it's a type of reflection from the sun or another strange phenomenon.
