This flare may be occulted due to its location near the west limb. | |

| Coronal mass ejection — 2026-09-24 14:45 UTC | Coronal mass ejection | — | 493 km/s | 1 | — | GOES: CCOR-1, STEREO A: SECCHI/COR2 | CME observed to the SW in GOES CCOR-1 and S in STEREO A COR2, overlapping with a slow, wide streamer blowout beginning ~2026-09-23T20:12Z (itself measuring ~176 km/s). Not observed in SOHO LASCO C2/C3 due to a real-time data gap. The source is field line movement and small shifting of a coronal hole boundary best observed only in GOES SUVI 284 starting ~2026-09-24T14:02Z, tracing on-disk around S35W70 in proximity to a large southern coronal hole. | |
| Coronal mass ejection — 2026-09-25 17:45 UTC | Coronal mass ejection | — | 462 km/s | 1 | — | GOES: CCOR-1, SOHO: LASCO/C3 | Faint CME that looks to consist of two loops moving together as one. It is seen faintly to the NE in GOES CCOR-1 and SOHO LASCO C3 difference imagery, moving in the footsteps of 2026-09-25T11:09Z CME. No coronal signatures have been found for this event, so it is likely far-sided. | |
| Coronal mass ejection — 2026-09-25 20:45 UTC | Coronal mass ejection | — | 460 km/s | 1 | — | GOES: CCOR-1, SOHO: LASCO/C3 | A narrow CME seen to the NE in GOES CCOR-1/SOHO LASCO C3 with a pointed front. It is not seen in STEREO A COR2 and SOHO LASCO C2 currently because of a data gap. No coronal signatures have been found for this CME in EUV imagery, except for possibly some movement of field lines to the NE seen in GOES SUVI 284. | |
| Coronal mass ejection — 2026-09-26 20:00 UTC | Coronal mass ejection | — | 336 km/s | 1 | — | GOES: CCOR-1, SOHO: LASCO/C3 | A minor faint CME seen to the NE in GOES CCOR-1 and SOHO LASCO C3, and not seen in STEREO A COR2 coronagraph. No source has been found in EUV imagery for this CME, so it is likely far-sided. | |
| Coronal mass ejection — 2026-10-09 00:45 UTC | Coronal mass ejection | — | 293 km/s | 1 | — | GOES: CCOR-1 | CME faintly seen to the east in GOES CCOR-1 imagery. There is a data gap in SOHO LASCO C2/C3 imagery starting at 2026-10-09T00:48Z and a data gap starting in STEREO A COR2 at 2026-10-09T00:53Z. The source is likely beyond the E limb as seen in available EUV imagery, as slow moving field lines are visible on the E limb in SDO AIA 193 and GOES SUVI 284 imagery starting as early as 2026-10-08T18:30Z. | |
| Coronal mass ejection — 2026-10-09 07:15 UTC | Coronal mass ejection | — | 391 km/s | 1 | — | GOES: CCOR-1 | CME seen to the NW in GOES CCOR-1 imagery. There is a data gap in SOHO LASCO C2/C3 and STEREO A COR2 at the time of this CME. The potential source is unclear, but is likely an eruption from AR 14547 (approximately N15W90) starting around 2026-10-09T06:30Z, best seen as moving/opening field lines in SDO AIA 193 and GOES SUVI 284 imagery. | |
| Coronal mass ejection — 2026-10-09 08:00 UTC | Coronal mass ejection | — | 270 km/s | 1 | — | GOES: CCOR-1 | CME visible to the NNW in GOES CCOR-1 imagery. There is no SOHO LASCO C2/C3 or STEREO A COR2 data available during this time, with a data gap in SOHO imagery starting at 2026-10-09T00:48Z and no STEREO A COR2 data available since 2026-10-09T01:09Z. The source for this CME is not found in available EUV imagery. |

- 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.
