A geomagnetic storm that began late on September 14, 2025, intensified to G3 – Strong levels early on September 15, producing auroras visible as far south as Texas. The storm was driven by a negative polarity coronal hole high-speed stream (CH HSS) with possible influence from a coronal mass ejection (CME) launched on September 11.
A fireball-like luminous event was observed over Weifang and Rizhao in Shandong Province, China, between 12:45 and 13:02 UTC on September 12, 2025. Videos showed a bright object crossing the night sky followed by a flash, leading to speculation on social media that it was intercepted or shot down.
A fireball with an impact energy of 0.38 kilotons (380 tons of TNT equivalent) was detected at 22:26 UTC on September 13, 2025, at an altitude of 22.8 km (14.2 miles) over central Argentina. The event was observed from multiple provinces and produced a persistent trail and visible fragmentation.
A long-track tornado was confirmed northeast of Montezuma Creek in San Juan County, Utah, between 12:30 and 13:05 MDT on September 13, 2025, about 10–13 km (6–8 miles) northeast of Montezuma Creek and 35 km (22 miles) southeast of Blanding. The National Weather Service issued a tornado warning for southeastern Utah and western Colorado.
A G1 – Minor Geomagnetic Storm Watch was issued by NOAA’s Space Weather Prediction Center for September 14, 2025, anticipating weak power grid fluctuations, minor satellite impacts, and possible auroras at high latitudes. No storm activity is forecast for September 15 and 16.
New activity/unrest was reported for 5 volcanoes from September 3 to 9, 2025. During the same period, ongoing activity was reported for 21 volcanoes.
A newly discovered comet, designated SWAN25B, emerged from behind the Sun in early September 2025 and was added to the Minor Planet Center’s Possible Comet Confirmation Page on September 12. The object is currently reported at magnitude 8.3 in MPC data, with independent amateur estimates placing it slightly brighter at magnitude 7.4–7.5. Orbit calculations are still in progress.
Tropical Storm Mario formed at 15:00 UTC on September 12, 2025, just off the coast of Mexico, prompting the government of Mexico to issue a Tropical Storm Watch from Lazaro Cardenas to Punta San Telmo. At the time of formation, the center of Mario was located 65 km (40 miles) SSW of Zihuatanejo and 95 km (60 miles) SSE of Lazaro Cardenas, Mexico.
A La Niña Watch was issued by NOAA’s Climate Prediction Center on September 11, 2025, with a 71% probability of La Niña forming in October–December 2025. Chances decline to 54% for December 2025–February 2026.
Weak to moderate lahars descended from Fuego volcano, Guatemala, at 19:17 LT on September 10, 2025, moving through Barranca Ceniza and into the Zarco and Mazate rivers, tributaries of the Achíguate River. The National Institute of Seismology, Volcanology, Meteorology and Hydrology (INSIVUMEH) reported that conditions remain favorable for additional lahars on the southwestern flanks.
