These two flares are in close succession, but visually separable in SDO AIA 131 and in their respective field line movements in SDO AIA 171. | |

These two flares are in close succession, but visually separable in SDO AIA 131 and in their respective field line movements in SDO AIA 171. | |

| Solar flare — 2026-10-09 13:55 UTC (M1.3) | Solar flare | M1.3 | — | — | 2026-10-09T14:36:00-CME-001 | GOES-P: EXIS 1.0-8.0 | Region 14547 decayed to a plage on 2026-10-08 and rotated off of the Earth-facing disk early on 2026-10-09. This flare may be occulted due to its location near the west limb. | |

Coverage of this source
- NASA DONKI — Space Weather Events: DONKI events in the look-back window (30 days by default), re-read every hour; older entries remain from earlier refreshes or an optional backfill.
NASA DONKI — Space Weather Events
Source: Data: NASA Community Coordinated Modeling Center (CCMC), DONKI; analyses by the Moon to Mars Space Weather Analysis Office. Last successful refresh: 14 Oct 2026, 16:02 EDT.
- DONKI information is supplied for research and analysis. It is not an operational emergency-warning service: NOAA's Space Weather Prediction Center (swpc.noaa.gov) is the official US source of space weather forecasts and warnings.
- Observations, analyses (a CME can have several, with the one DONKI marks most accurate), model predictions (WSA-ENLIL) and notifications are shown as such, in their original units and classifications. No combined severity score is computed.
- Times are UTC as supplied. DONKI revises entries; the look-back window is re-read on every refresh.
