X1.7 solar flare
Sunday, 9 November 2025 19:55 UTC
The anticipated coronal mass ejection (CME) impacts did not really materialize as expected with only one true clear impact back on Friday. Are we in residual CME effects? Possibly but geomagnetic conditions are currently a far cry from the expected moderate to strong storm conditions.
X1.7 solar flare with coronal mass ejection
Sunspot region 4274 has been relativity quiet but that changed this morning around 07:30 as it erupted with an X1.7 (R3-strong) solar flare. The sunspot region keeps its complex Beta-Gamma-Delta magnetic layout which means it remains capable of M and X-class solar flares as it starts to rotate towards the west limb.
A halo coronal mass ejection was detected following the eruption which likely has an earth-directed component. NOAA's ENLIL solar wind model expects this coronal mass ejection to arrive late on Tuesday, 11 November and issued a Moderate G2 geomagnetic storm watch for both Tuesday the 11th and Wednesday the 12th of November.
