December 2025 witnessed escalating solar activity within Solar Cycle 25. Early in the month, a full-halo coronal mass ejection from an M8.1 flare on December 6 led to a strong G3 geomagnetic storm on December 9, enhancing auroral displays. Mid-month featured an X1.1 flare on December 8 — the most intense of the period — along with multiple C- and M-class flares.
Activity intensified late, with an M5.1 flare on December 27, an M4.2 on December 28, and peaking at an M7.1 on December 31, accompanied by potential Earth-grazing CMEs. Sunspot clusters and coronal hole high-speed streams contributed to minor geomagnetic disturbances throughout the period.
We can anticipate additional extreme weather, earthquakes, and increased solar activity over the next few months.
December 2025 was marked by severe flooding and landslides in Southeast Asia, resulting in over 1,500 fatalities across Sri Lanka and Indonesia, alongside notable seismic activity, including a 7.6 magnitude earthquake off Japan's east coast that prompted a tsunami warning.
Volcanic eruptions occurred at Mount Semeru in Indonesia and mud volcanoes in India and Trinidad, while unseasonal snowfalls and cold snaps affected regions from Australia to Canada. Multiple meteor fireball sightings were reported globally, and extreme weather events like atmospheric rivers and storms caused widespread disruptions in North America and Europe.
Comment: Social media in Argentina is rife with reports of evidence of arson at more than one of the fires:
And Argentine media is reporting the discovery of 'grenades' of some type being found 'around a lake' somewhere in Patagonia:
DD Geopolitics has a whole theory as to what may be happening here: preparation for partitioning Argentina into another 'Jewish state'?
