China to Send Second 'Xihe' Solar Observatory to Sun‑Earth L5 for Earlier Space‑Weather Warnings
China plans to launch a second solar observatory, Xihe‑2, to the Sun‑Earth L5 point in 2028–2029 to deliver stereoscopic and multi‑band observations of the Sun. The mission aims to improve early warning of solar storms, bolster China’s heliophysics capabilities and strengthen operational space‑weather forecasting.
Small Sparks, Massive Storms: ESA Identifies 'Magnetic Avalanche' as Trigger for Solar Flares
The European Space Agency reports that solar flares can be triggered by a cascade of tiny, rapid magnetic disturbances that amplify into a "magnetic avalanche." This emergent mechanism reframes flare onset as a scale-crossing process and could improve space-weather forecasting if validated and incorporated into monitoring systems.
Spectacular Auroras Over China as a Major Geomagnetic Storm Rocks Earth
A major geomagnetic storm caused auroras to appear across large swathes of China, delighting onlookers but also raising concerns about impacts to satellites, communications and power systems. The event highlights ongoing solar activity and the need for robust space-weather monitoring and infrastructure resilience.
