Geomagnetic Storm Watch: Moderate Activity Forecast for Jan 10–11, 2026
NOAA's Space Weather Prediction Center forecasts periods of G1–G2 (Minor–Moderate) geomagnetic activity on Jan 10–11, 2026 as a CME released on Jan 8 arrives, signaling a moderate geomagnetic storm risk with potential effects on space- and radio-related operations.
Scientists Break Records Studying the Sun's Most Active Region
Astronomers set a new record by continuously observing the Sun's active region NOAA 13664 for over 90 days using two spacecraft, providing valuable insights into solar activity and improving space weather predictions.
Record-Breaking Solar Activity Unveiled by Recent Observations
A record-breaking study revealed that the giant sunspot AR 13664, which grew to 15 times Earth's width, produced nearly 1,000 solar flares, including powerful X-class flares, and triggered Earth's most intense geomagnetic storm in over 20 years, highlighting the sun's immense power during solar maximum.
Earth Faces Major Solar Storms and Magnetic Activity in Early January 2026
NOAA has issued G1-G2 watches for January 3-4 due to expected CMEs from solar activity, which may cause minor to moderate geomagnetic storms, affecting HF radio and navigation signals.
Northern Lights to Shine Over Multiple U.S. States This Week
The northern lights may be visible in 18 U.S. states tonight due to a coronal mass ejection from the sun, with the best viewing times between 4 p.m. and 4 a.m. EST, especially in areas with dark, clear skies. Viewers are advised to find a north-facing vantage point, avoid light pollution, and let their eyes adapt to the dark for optimal viewing.
NASA Develops Robots to Support Human Life on Mars
NASA is developing robotic systems and tools, such as real-time space weather dashboards and radiation mapping, to support human missions to Mars and the Moon, while also addressing challenges like lunar dust and water detection, emphasizing a collaborative approach between robots and humans for future exploration.
Magnetic Storms in January 2026: Forecast and Peak Days
NOAA has issued G1 to G2 watches from January 1-3, 2026, indicating expected increased geomagnetic activity due to coronal mass ejections (CMEs), which may cause minor to moderate disruptions in HF radio and navigation signals.
Preparing Robotic Explorers for Human Mars Missions
Scientists are leveraging existing space missions and data to prepare robotic explorers for future human missions to the Moon and Mars, focusing on water resource identification, radiation shielding, and dust management, with new tools and instruments being developed to address these challenges.
Recent Solar Flares and Their Impact on Earthly Technology
A significant M7.1 solar flare occurred on December 31, 2025, originating from sunspot region 4324, accompanied by a coronal mass ejection (CME) that is expected to cause minor G1 geomagnetic storm conditions on Earth by January 2, 2026, with the majority of the CME heading away from Earth.
