The filaments present on the Sun are clouds of solar material, which, due to the powerful magnetic force, keep hovering over it. According to the US space agency NASA, these filaments are considered extremely unstable and can exist for several days or weeks.
According to SpaceWeather.com, solar filaments were first observed on July 12, when astronomers observed dark thread-like lines next to the bright background of the Sun. Then on 15 July, a filament moved into the Sun’s northern hemisphere before erupting, creating a huge valley of fire, measuring 3,84,400 km in length and 20,000 km in depth. This valley sent solar material towards our planet.
Such solar filaments can push dangerous solar winds (solar wind) in the direction of Earth, called coronal mass ejections (CMEs). Solar storms are classified as G1, G2, and G3 in increasing order of their strength.
Space meteorologist Dr Tamitha Skow also shared her Tweet In this, information was given about the possibility of a solar storm hitting the Earth.
It was also said that this G1 storm had caused fluctuations in power grid lines. Not only this, the satellite functions were reportedly affected as well.
