Active Region 4274 produced its second X-class solar flare since it emerged from the far side last week, this time peaking as X1.2 at 09:19 UTC on November 10, 2025. This is now the third X-class flare since the November 4 X1.8 and X1.1. A coronal mass ejection (CME) was associated with the latest event and is expected to have an Earth-directed component.
Super Typhoon Fung-wong (known locally as Uwan) made landfall over Dinalungan, Aurora, northern Luzon, at about 21:10 LT (13:10 UTC) on November 9, 2025, with maximum sustained winds near 185 km/h (115 mph) and gusts up to 230 km/h (143 mph). More than 1.1 million people were pre-emptively evacuated across 12 regions, and at least two fatalities and two injuries have already been confirmed.
A major long-duration solar flare measuring X1.7 erupted from Active Region 4274 at 07:35 UTC on November 9, 2025, producing an assymetric halo CME with impact expected around 12:00 UTC on November 11. The event started at 07:01 and ended at 07:55 UTC.
A powerful tornado struck the municipality of Rio Bonito do Iguaçu, Paraná, southern Brazil, in the late afternoon of November 7, 2025, killing at least five people and injuring over 130, of whom 30 were seriously injured. Winds exceeding 240 km/h (150 mph) destroyed most of the town’s structures, prompting a large-scale emergency response by Civil Defense, the Fire Department, and state authorities.
Severe Tropical storm Fung Wong intensified over the Philippines Sea on November 7, 2025, and is forecast to make landfall over the Philippines over the weekend.
The Philippine government declared a state of calamity on November 6, 2025, after Typhoon Kalmaegi left 114 people dead, 127 missing, and displaced more than 560 000 residents while flooding parts of the Visayas, according to the National Disaster Risk Reduction and Management Council (NDRRMC).
Solar activity reached high levels on November 5, 2025, as Region 4274 (N24E40) produced two powerful M-class flares – an M7.4 at 11:19 UTC and an M8.6 at 22:07 UTC. The full-halo CME from the first event is expected to reach Earth late November 6 to early November 7, likely producing G3 – Strong geomagnetic storm conditions and visible auroras across Canada and the northern United States.
A record-breaking bomb cyclone ripped through Newfoundland from November 4 through 5, 2025 bringing along Category 2 hurricane force winds, coastal flooding, and causing widespread damage across the region.
An early-season stratospheric warming event is forecast to weaken the polar vortex in the coming weeks, potentially influencing winter 2025–26 weather across North America and Europe.
Two powerful X-class solar flares erupted on November 4, 2025 — an X1.8 from Region 4274 and an X1.1 from a region just beyond the east limb — launching CMEs largely off the solar limb. NOAA forecasts G1 – Minor to G2 – Moderate geomagnetic storming from late November 6 into 7 as Earth may experience a glancing shock from the flares combined with a coronal hole high-speed stream.
