The increase in solar activity is due to the Sun moving closer toward the peak of its Solar Cycle. The Solar Maximum, as it is known, will not be reached till the end of 2024 or the beginning of 2025. This increased solar activity has resulted in sunspots, solar flares, and CME clouds reaching potentially damaging intensities to the point that they can actually damage our tech infrastructure. To make matters worse, it has also pushed seemingly harmless solar phenomena into destructive forces as well. For example, magnetic filaments have always existed. Yet, recently, a huge number of them have been spotted on the Sun, creating fears of a dangerous solar storm striking our planet.
The information comes from a report by SpaceWeather.com which noted that a new photo taken by an astrophotographer highlighted more than a dozen of magnetic filaments on the Earth-facing side of the Sun. “The most important filament is the extremely long one stretching across the sun’s high-northern hemisphere. Parts of it have been exploding for days. With so many filaments on the sun, a geoeffective CME may be just a matter of time”. And it is not just pure speculation. The long filament has already exploded twice on April 15 and April 17, releasing a huge amount of coronal mass ejection (CME) cloud into space.
Magnetic filaments on Sun give a solar storm warning
For the unaware, a magnetic filament is a large plasma and magnetic field structure extending outward from the Sun’s surface, often in a loop. These eruptions contain high radiation and are powerful enough to push out CME into space. On April 15, it shot a small cloud of CME toward the Earth. But due to low intensity, it failed to give rise to a geomagnetic storm today, April 19, when the CME made the impact.
Such filaments can both cause shortwave radio blackouts when they erupt and later cause geomagnetic storms when the CME particles reach Earth. With the intensifying solar weather, such solar storms can damage satellites, disrupt mobile networks, internet services and GPS signals, cause power grid failures and even corrupt sensitive electronics on Earth.
For now, we can only wait and watch whether any of these magnetic filament goes unstable and erupts or not.
