Nicole Sharp<p><strong>See the Solar Wind</strong></p><p>After a solar prominence erupts, strong solar winds flow outward from the sun, carrying energetic particles that can disrupt satellites and trigger auroras if they make their way toward us. In this video, an instrument onboard the ESA/NASA’s Solar Orbiter captures the solar wind in the aftermath of such an eruption. The features seen here extended 3 solar radii and lasted for hours. The measurements give astrophysicists their best view yet of this post-eruption relaxation period, and the authors report that their measurements are remarkably similar to results of recent magnetohydrodynamics simulations, suggesting that those simulations are accurately capturing solar physics.

Sun activity is high, thanks to the X4.5 flare – the day’s largest flare – at 15:29 UTC on September 14 from sunspot region AR3825. Earth should start receiving fast #SolarWind beginning September 15. https://earthsky.org/sun/sun-news-activity-solar-flare-cme-aurora-updates/
