NASA and NOAA said this week that the sun has officially reached Solar Maximum, the peak of its 11-year cycle. NASA heliophysicist C. Alex Young and EarthSky’s founder Deborah Byrd talked about it on this week’s Friday livestream, our Sun News of the Week. Watch in the player above, or on YouTube.| EarthSky

Sun news September 30: Happy perihelion, Parker Solar Probe!| EarthSky
Our active sun continues to disturb Earth’s geomagnetic field. At the time of this writing a G1 (minor) geomagnetic storm is ongoing. The threshold was reached at 9:15 UTC. We saw activity the whole time during our observation period between 11 UTC yesterday and 11 UTC today. Late yesterday and early today we saw another G1 disturbance, during the 0-3 UTC period. People have reported auroral displays in Europe, Canada and the U.S. The G1 storming occurred during the dark hours in the U.S. ...| EarthSky
Cannibal CME A double load of plasma. It occurs when two CMEs erupt off the sun at the same time. If the second CME overtakes and consumes the first, a CME combination forms. Cannibal CMEs contain tangled magnetic fields and compressed plasmas, which can cause severe geomagnetic storms.| EarthSky
Artist’s concept of activity on the sun traveling across space, to interact with Earth’s magnetic field. Not to scale. The sun’s activity can cause a geomagnetic storm, which aren’t harmful to humans, but which can harm earthly technologies.

View at EarthSky Community Photos. | Mario Rana in Hampton, Virginia, captured this filtered image of the sun on July 17, 2024. Thank you, Mario! According to new research, the next solar cycle is already beginning, despite the fact that the sun’s only halfway through its current cycle.| EarthSky
Sun activity is high this week, so far. There were 7 M flares in the past day. And check out the newcomer on the sun’s eastern, or incoming, side. Remember sunspot region AR3738? It produced an X flare and numerous M and C flares during its trip across the Earth-facing sun from July 5 to 17. Then the sun’s rotation carried it to the far side, where it produced an X14 flare! The flare – and its effects – were observed thanks to the Solar Orbiter spacecraft, which can see the sun’s fa...| EarthSky

On New Year’s Eve 2023, the sun blasted a huge X flare, the biggest of solar cycle 25 so far. It came from sunspot region AR3536 and measured X5 on the solar flare intensity scale. The eruption produced a wave that rippled across the sun’s face in all directions. It produced a coronal mass ejection, or CME, a great clump of superheated matter that left the sun and traveled outward into our solar system. | EarthSky
Sun news for November 12-13, 2024. NOAA is forecasting active (kp=4) geomagnetic conditions for tonight and tomorrow, with the possibility of a G1 storm (Kp=5). This is due to fast solar wind from a coronal hole on the Earth-facing solar disk. Image via NOAASun news November 13: Auroras possible tonight and tomorrow| EarthSky
View at EarthSky Community Photos. | Lana Froemming of Marengo, Wisconsin, captured this image on September 18, 2023, not long before the September equinox. She wrote: “I saw the magic in the sky. I watched the amazing light show from about 8:45 p.m. until about 11:30 p.m. … ” Thank you, Lana! The weeks around the fall and spring equinoxes are recognized by scientists as aurora season. We have more auroras at that time of year than any other time. Keep reading to find out why.When is a...| EarthSky
