| Coronal mass ejection — 2026-10-14 13:36 UTC | Coronal mass ejection | — | 236 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | Bright CME first seen to the NE by SOHO LASCO C2 beginning at 2026-10-14T13:36Z, as well as by SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1 in later frames. The source of this event is a filament eruption centered at approx. N45E20 seen beginning at approx. 2026-10-14T10:05Z in SDO AIA, GOES SUVI and STEREO A EUVI 304 imagery. Dimming and field line opening can also be seen in SDO AIA 171/193, GOES SUVI 284 and STEREO A EUVI 195 imagery. | |
| Coronal mass ejection — 2026-10-14 23:12 UTC | Coronal mass ejection | — | 360 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME first seen to the NE by SOHO LASCO C2 beginning at 2026-10-14T23:12Z. The source of this event is a large filament eruption seen originating from beyond the NE limb in GOES SUVI 304 imagery beginning at approx. 2026-10-14T21:52Z. Field line opening is also seen in GOES SUVI 284 in association with this eruption. | |
| Coronal mass ejection — 2026-09-25 20:06 UTC | Coronal mass ejection | — | 254 km/s | 1 | — | SOHO: LASCO/C3, GOES: CCOR-1 | A minor, narrow CME seen to the E in GOES CCOR-1/SOHO LASCO C3. It is not seen in STEREO A COR2. No coronal signatures have been found for this CME in EUV imagery. | |

| Coronal mass ejection — 2026-09-14 11:08 UTC | Coronal mass ejection | — | 897 km/s | 2 | 2026-09-17T01:24:00-IPS-001, 2026-09-17T15:10:00-IPS-001 | STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME first seen to the E in STEREO A COR2 starting at 2026-09-14T11:08Z. It is also seen to the W in GOES CCOR-1. This CME is covered by a data gap in SOHO LASCO C2/C3 in real time. The source of this CME is an eruption centered around AR 14528 (S11W38) best seen in GOES SUVI 284 beginning around 2026-09-14T10:00Z. Field line movement can be seen accompanied by brightening and ejecta. Post-eruptive arcades can also be seen in SDO AIA 193. There seems to be a northwestward deflection from the location of the source. There are two large coronal holes (a northern and a southern one) nearby, possibly responsible for this deflection. | |
| Coronal mass ejection — 2026-09-20 12:23 UTC | Coronal mass ejection | — | 427 km/s | 1 | — | STEREO A: SECCHI/COR2 | Faint CME observed to the W only in STEREO A COR2. No distinct source is observed in available EUV imagery. |

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
Data: NASA Community Coordinated Modeling Center (CCMC), DONKI; analyses by the Moon to Mars Space Weather Analysis Office. Last successful refresh: 15 Oct 2026, 16:51 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.
