MAGNETIC QUIET: The solar wind blowing around Earth is thin and steady, which means it is doing little to rattle our planet's magnetic field. Geomagnetic storms are unlikely during the next 24 hours.
EMERGING BLAST SITE: A farside sunspot that exploded and hurled a bright CME into space on Sept. 23rd is now rotating onto the Earthside of the sun. NASA's Solar Dynamics Observatory photographed the emerging blast site during the early hours of Sept. 26th:
Because the sunspot is still near the sun's eastern horizon, foreshortening prevents a clear view of its core magnetic structure. The events of Sept. 23rd, however, suggest that this could be a potent active region. Stay tuned for updates as the sunspot turns toward Earth. Solar flare alerts: text, voice.
