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.
Solar Flare Causes Minor Auroras Worldwide
AI에 의해 보고됨
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.
Fast Solar Wind Triggers Aurora Displays

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 Filaments Erupt from Sun's Surface
On September 11 and 12, 2025, astronomers observed significant filament activity on the Sun, with plasma lifting off in the northern and southeastern regions. Despite low flaring activity limited to C-class flares, the events provided a spectacular display of solar dynamics. This activity highlights ongoing solar monitoring efforts amid a period of relatively calm sunspot behavior.
