Fast Solar Wind Triggers Aurora Displays
Von KI berichtet
A coronal hole on the Sun has released fast solar wind, potentially causing aurora sightings in northern latitudes. The event is expected to peak tonight. Space weather experts are monitoring the impacts on Earth.
Solar Flare Causes Minor Auroras Worldwide
Von KI berichtet
A solar flare from the sun's southeast filament activity has led to minor auroral displays visible in northern latitudes. This event, occurring on September 15, 2025, is expected to have minimal impact on Earth's atmosphere but highlights ongoing solar dynamics. Scientists monitor such events for potential effects on satellite communications.
Discovery of Solar Electron Acceleration Mechanisms
Scientists have uncovered hidden engines responsible for solar electron acceleration, addressing space weather risks. The findings were reported on September 3, 2025. This advances understanding of solar phenomena.
Scientists uncover cause of rapid solar rain during flares
Researchers at the University of Hawaiʻi Institute for Astronomy have solved the mystery of why solar rain forms so quickly during solar flares. Their work reveals that changing elemental abundances, like iron, enable the rapid cooling of plasma in the Sun's corona. This breakthrough could enhance predictions of space weather impacts on Earth.
