Prof. YAN Yihua and his research team from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) recently released detailed results of observations by the new generation solar radio telescope-Mingantu Spectral Radio Heliograph (MUSER)-from 2014 to 2019.
The study was published in Frontiers in Astronomy and Space Sciences on March 29. It may help us better understand the basic nature of solar eruptions.
Solar radio bursts are associated with different types of powerful eruptions like solar flares, coronal mass ejections, and various thermal and nonthermal processes. They are prompt indicators of disastrous space weather events.
Solar radio observations, especially at centimeter and decimeter wavelengths, play an important role in revealing the key physics behind primary energy release, particle acceleration and transportation. They also help identify crucial precursors of solar storms.
Synopsis
A software named Computer Aided CME Tracking Software based on a computer vision algorithm was so far used to detect and characterise such eruptions automatically in the outer corona where these eruptions cease to show accelerations and propagate with a nearly constant speed.

Scientists have developed a new technique to track the huge bubbles of gas, threaded with magnetic field lines, which are ejected from the sun disrupting space weather and causing geomagnetic storms, satellite failures, and power outages, the Department of Science and Technology said Thursday.
The new technique will be used in India s first solar mission Aditya-L1.

The new technique will be used in India s first solar mission Aditya-L1.
As the ejections from the sun, technically called Coronal Mass Ejections (CMEs), cause various disturbances of the space environment, forecasting their arrival time is very important. However, forecasting accuracy is hindered by limited CME observations in interplanetary space, the DST statement said.
