Generated UTC: 2026-06-30 04:52:58 UTC

Situation snapshot

Current snapshot: CME watch route active / recent M-class flare history / central-disc region relevance present. The rolling weekly audit shows 65 unique flare events from 5 active regions, split C=63, M=2, X=0.

The largest event in the current rolling activity window is M1.4 from AR4479 at N16W12, recorded around 2026-06-29 21:13:00 UTC.

GOES X-ray trend is not resolved into this commentary cycle.

Active-region commentary

AR4479: flare-productive and unsettled; 19 event(s) in the rolling window, maximum M1.4. It is crossed the central disc (N15E62 to N16W12). Current inferred position from the activity journey is N16W12, giving central-disc / strongest Earth-facing relevance. Morphology/regime note: McIntosh morphology currently Eki; Hale class βγδ.

AR4475: flare-productive and unsettled; 23 event(s) in the rolling window, maximum M1.3. It is crossed the central disc (S08E25 to S09W49). Current inferred position from the activity journey is S09W49, giving west-disc / moderate Earth-facing relevance. Morphology/regime note: McIntosh morphology currently Dai; Hale class βγδ.

AR4478: persistent C-class pressure; 18 event(s) in the rolling window, maximum C8.8. It is rotating in from the east limb toward the central disc (S07E67 to S05E08). Current inferred position from the activity journey is S05E08, giving central-disc / strongest Earth-facing relevance. Morphology/regime note: McIntosh morphology currently Fki; Hale class βγ; state WATCH.

AR4477: low-cadence / watch-only; 3 event(s) in the rolling window, maximum C4.3. It is rotating in from the east limb toward the central disc (S12E65 to S14E03). Current inferred position from the activity journey is S14E03, giving central-disc / strongest Earth-facing relevance. Morphology/regime note: McIntosh morphology currently Bxo; Hale class β.

AR4473: low-cadence / watch-only; 2 event(s) in the rolling window, maximum C3.9. It is crossed the central disc (S09E26 to S07W04). Current inferred position from the activity journey is S07W04, giving central-disc / strongest Earth-facing relevance.

Earth-facing relevance

Limb-to-asset pathway: WATCH.

CME / impact route

CME/impact route: route state valid; source N16W04; associated flare M1.4; speed about 526.0 km/s; width 18.0 deg; arrival window ETA 07-03 11Z; G1 / Kp 3-5 watch; confidence Moderate.

Primary CME focus: AR4479 / N16W04; 526 km/s; width 18 deg; G1 / Kp 3-5 watch.

Solar wind / geomagnetic

Solar-wind and Kp fields are not resolved into this commentary cycle; do not infer coupling from this page alone.

What to watch next

  • Watch AR4479 for repeat flare cadence while it remains central-disc / strongest Earth-facing relevance.
  • Watch AR4475 for repeat flare cadence while it remains west-disc / moderate Earth-facing relevance.
  • Watch AR4478 for repeat flare cadence while it remains central-disc / strongest Earth-facing relevance.
  • Watch AR4477 for repeat flare cadence while it remains central-disc / strongest Earth-facing relevance.
  • Track any change to the CME arrival window, Kp branch, or Earth-directed confidence.
  • Check whether GOES X-ray flux is rising, falling or flattening before treating flare cadence as increasing.
  • Use the Dark Ops panels for formal source geometry, impact routing and asset-risk confirmation.
