Solar radiation storm, CME produced by M4.2 flare expected to hit Earth on May 11

High solar activity was observed on May 10, 2023, primarily due to the enhanced flare potential of Region 3296. The most significant event from the region was an M4.2 flare, which resulted in a well-defined partial halo Coronal Mass Ejection (CME) signature, expected to hit Earth sometime after 18:00 UTC on May 11. The 10 MeV proton flux peaked at 38 pfu, dropped below Minor – S1 solar radiation storm levels by 12:35 UTC on May 9, but still above average, and then rose back over the 10 pfu threshold due to the May 7 CME passage.

CME impacts Earth, sparking G3 – Strong geomagnetic storm

CME impacts Earth, sparking G3 – Strong geomagnetic storm

Coronal mass ejection (CME) produced by a long-duration M3.7 solar flare at 20:30 UTC on February 24, 2023, reached Earth at 19:25 UTC on February 26. A glancing blow impact from CME produced by M6.3 solar flare on February 25 is expected during the afternoon hours on February 27. The resulting geomagnetic storm activity is expected to be significant, with both CMEs interacting with a negative-polarity coronal hole high-speed stream, potentially producing G3 – Strong or higher levels of geomagnetic storming.

Earth hit by slow-moving CME, triggers G1-Minor geomagnetic storm; second CME on the way

Earth hit by slow-moving CME, triggers G1-Minor geomagnetic storm; second CME on the way

A slow-moving coronal mass ejection (CME) that left the sun on February 11, 2023, reached our planet today, causing G1 – Minor geomagnetic storming. A partial halo CME, possibly triggered by a filament eruption near Region 3220 on February 14 is forecast to impact Earth this week, which could result in disruptions to communication networks, power grids, and satellites. The timing and extent of the impact are still being analyzed.

G2 – Moderate geomagnetic storm watch in effect

A G2 – Moderate geomagnetic storm watch is in effect for February 2, 2022, after a long-duration M1.1 solar flare produced an asymmetric, full-halo coronal mass ejection (CME) at 23:32 UTC on January 29. The CME is expected to reach Earth late February 1 or early…

Glancing-blow expected after weak B1.2 solar flare

Glancing-blow expected after weak B1.2 solar flare

A weak solar flare measuring B1.2 at its peak erupted on August 16, 2020, producing a coronal mass ejection (CME). Consensus model results suggest an arriving glancing blow on August 20 — producing unsettled to active geomagnetic field conditions, with a chance for…
