Chinese authorities are completing construction of a telescope array in Tibet that forms a 3.14 km circle.
Daocheng Solar Radio Telescope (DSRT)is being built on a plateau in Sichuan province in southwestern China. The finished array will consist of 313 plates with a diameter of 6 m, arranged in a circle. According to the plan, the construction of the telescope should be completed before the end of 2022.

An array of telescopes will display the Sun atradio waves to study coronal mass ejections, large ejections of charged particles from the solar corona. The study will help to better assess the impact of the activity of our star on the weather on Earth, predict the approach and likely consequences of solar storms.
DSRT is part of a larger Chinesemeridian” (phase II), aimed at creating a network of ground-based instruments that explore space. The entire project aims to launch some 300 instruments deployed at 31 stations across China.
Among them, in addition to the largest radio telescope,for example, there will be a spectral radioheliograph to monitor solar activity in Inner Mongolia. It will consist of 100 plates arranged in a spiral with three arms. This device will study the Sun in a wider range, which, as the developers believe, together with DSRT, will give the most complete picture of the star's activity.
