In preparation of the start of FAST's formal operation this year, the rules for visitors of Five-hundred-meter Aperture Spherical Telescope (FAST) were reinforced.
No cell phones, no digital cameras, and no smart wearable devices - the Guizhou provincial government has revised a regulation to keep the noise down and prevent human activities from affecting the world's largest telescope. The total quiet area of FAST includes a 5 km radius as the core zone, 5 km to 10 km radius as the intermediate zone and a peripheral zone that covers 10 km to 30 km in radius. The regulation is expected to be effective starting from 1 April 2019.
