Rain is a common phenomenon on Earth. There is a similar phenomenon on the Sun, called coronal rain. It is related to the coronal heating and magnetic field, and plays a fundamental role in the mass cycle between the hot, tenuous corona and the cool, dense chromosphere.
Coronal rain usually takes place in post-flare loops and the non-flaring active region coronal loops. It is generally classified into two categories: flare-driven and quiescent coronal rain, depending on its relation to the flare. Both kinds of coronal rain form along structures that are magnetically closed.
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.

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.
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.
