A Type II Radio Emission with an estimated velocity of 1 321 km\/s was observed at 09:11 UTC, suggesting a CME was produced during today\u2019s X1.2 solar flare.<\/p>\n
Additionally, a Type IV Radio Emission was associated with the flare event, suggesting a strong CME was produced. With the source region still in a geoeffective position, an Earth-directed CME seems very likely.<\/p>\n
Radio frequencies were forecast to be most degraded over Africa, parts of the Middle East, and the Indian Ocean.<\/p>\n
Region 4274 still has a \u2018beta-gamma-delta\u2019 magnetic configuration and is capable of producing more major eruptions on the Sun. Earth-directed CMEs from this region remain likely in the days ahead.<\/p>\n<\/noscript>X1.2 solar flare on November 10, 2025.

Image credit: SWPC<\/figcaption><\/figure>\n<\/div>\nSolar activity was at high levels over in 24 hours to 00:30 UTC on November 10. Region 4274 produced an X1.7\/2b flare at 07:19 UTC on November 9, associated with Type II (804 km\/s) and Type IV radio sweeps, as well as an F10.7 cm radio burst measuring 360 solar flux units (sfu).<\/p>\n
The resulting asymmetric halo CME, first observed in LASCO C2 imagery at 07:48 UTC off the north-northeast limb, is Earth-directed with an anticipated arrival around midday UTC on November 11.<\/p>\n<\/noscript>X1.7 solar flare on November 9, 2025.

The SWPC forecasts a 70% probability of M-class and a 25% probability of X-class solar flares through November 12.<\/p>\n

From November 10\u201312, the >2 MeV electron flux is expected to reach high levels. The >10 MeV proton flux could increase to S1 \u2013 Minor storm levels due to the activity and location of Region 4274.<\/p>\nImage credit: SWPC<\/figcaption><\/figure>\nSolar wind parameters over the past 24 hours reflected waning negative polarity coronal hole high-speed stream (CH HSS) influences. The total magnetic field strength reached 8 nT, with the Bz component fluctuating between \u00b16 nT. Solar wind speeds gradually declined from 600 km\/s to about 525 km\/s while the phi angle was variable throughout the period.<\/p>\n
Mild enhancement of the solar wind environment is likely on November 10 as the CME from November 7 passes near Earth. Stronger disturbances are expected between November 11\u201312 following the anticipated arrival of the November 9 CME.<\/p>\n

Periods of G1 \u2013 Minor geomagnetic storming are likely on November 10 due to possible CME-related enhancements from the November 7 event. More pronounced activity, ranging from G1 \u2013 Minor to G2 \u2013 Moderate levels, is expected between November 11\u201312 as Earth encounters the CME from November 9.<\/p>\n
