A solar storm is expected to hit Earth on Sunday and while it is going to be the first such incident of the month, experts believe that it could result in a partial blackout. A coronal hole has reportedly been opened up in the Sun which is releasing a huge swarm of cosmic particles, said a report in express.co.uk. 

A statement published on Space Weather website says, “Cutting across half of the solar disk, a wide hole in the sun's atmosphere is turning toward Earth and spewing a stream of solar wind toward our planet. This extreme ultraviolet image from NASA's Solar Dynamics Observatory shows the gaseous canyon”.

The image shows a coronal hole, which is a region where the sun's magnetic field opens up while allowing the gaseous material to escape. On the other hand, it looks dark because of the hot glowing gas that was previously contained there, is now missing, the website added.
