Fast Solar Wind Triggers Aurora Displays
Сообщено ИИ
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
Сообщено ИИ
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.
Solar polar observatory mission planned for 2029 launch
The Solar Polar-orbit Observatory (SPO) mission, set to launch in January 2029, will provide the first direct views of the Sun's polar regions. These areas, long hidden from Earth's orbital perspective, are key to understanding the solar magnetic cycle, fast solar wind, and space weather. The mission aims to address fundamental questions in solar physics through advanced imaging and in-situ measurements.
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.
