A powerful stream of energised particles (called solar storm) released by the Sun is headed towards the Earth that could lead to radio blackouts and aurora borealis or northern lights. According to NASA's spaceweather.com, the storm emanated from the sunspot AR3664 on May 27 and was a class X2.8, making it one of the most intense solar events in recent years. X-class solar flares are the strongest, which are described by NASA as "giant explosions on the sun that send energy, light and high speed particles into space".
Earth has already experienced interruption in shortwave radio due to the solar storm, but thankfully coronal mass ejection (CME) from the latest eruption will not impact our planet.
This starburst caused a huge coronal mass ejection to erupt on the side of the Sun facing away from us, Ryan French, a solar physicist at the National Solar Observatory in Boulder, Colorado, wrote on X.
A solar storm travels toward Earth at the speed of light and ionises (gives an electrical charge to) the top of the planet's atmosphere when it reaches us. This ionisation causes a higher-density environment for the high-frequency shortwave radio signals to navigate through to support communication over long distances.
After being hit by these charged particles, the electrons collide more frequently with the radio waves, leading to signals becoming degraded or completely lost.
There is more worry among the scientific community about AR3664, which is set to face the Earth again around June 6. The eruptions at that time could generate another set of geomagnetic storms with the potential to impact the Earth adversely.
