From a distance, there are 5 cheap beams of clouds in the sky.The amount of light from these rays is quite large, silhouetted on the water.The darker the night, the less expensive rays of the fans become darker, glare in the sky.(Photo: Nguyen Ba Ngoc).

Tia fans look at Bui Huu Nghia Bridge, Binh Thanh District. "When taking a photo, feeling Saigon is beautiful and peaceful , " said Hao Thai. After viewing these images, Mr. Le Dinh Quyet, Deputy Head of Meteorological Division of Southern Region Meteorological Station, said that this phenomenon looked quite interesting but nothing strange. This type of medium cloud is called Ac cloud (Altocumulus) , with an average height of 2.5-6 km.With this type of clouds often for good weather, no rain, occasionally appearing sun canopy or moon canopy.(Photo: Hao Thai Channel).

He decided to solve the color of red and yellow clouds because it was the time of sunset, when the sun was nearing the horizon. "Sunset" light wavelengths near red (0.64-0.76 mm or orange, wavelength 0.59-0.65mm). Fan-shaped clouds are due to light refraction, when the sun's position is low, meeting the cloud with a "special" shape , we imagine it is like shining a flashlight on something with a light-shaped object will scatter up creating such "special" images.(Photo: Nhon Vo).

Mr. Quyet concluded that this is only a very special " cloud " structure , but it is not a sign of dangerous weather but the weather is still normal, less likely to be rainy or sunny.(Photo: Jess Ho).
