SHANGHAI people may see blurry or frozen images and flickering white dots on their TV screens from time to time this Saturday because of overwhelming radiation from the sun, authorities said.
The phenomenon, known as sun outage, occurs when the sun, the earth, a satellite and a satellite ground station are aligned. It happens in the northern hemisphere before the March equinox and after the September equinox.
Television signals across China are expected to be interfered from now to March 17. The solar radiation will affect Shanghai for 11 days beginning from Saturday, according to the State Administration of Radio, Film and Television.
Sun outage may disturb satellites beaming signals toward Shanghai every day between 10am and 2:30pm, lasting about one to more than 10 minutes, it said.
"When that happens, some satellite channels will be cut off briefly," said Liu Jiuping, deputy general manager of Shanghai Oriental Cable Network.
"But local cable TV networks, Shanghai Dragon TV and CCTV channels won't be affected," he added.
