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.

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.

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.

A butterfly-shaped coronal hole appeared on the Sun, as reported in solar activity updates.

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.

Solar activity surged over September 7-8, 2025, including an M1.2 solar flare. This follows a period of relative calm and could impact space weather. Observations were reported by solar experts.
