- STEREO A: SECCHI/COR2, GOES: CCOR-1
CME visible to the NE in STEREO A COR2 and the NW in GOES CCOR-1. There was a real-time data gap in SOHO LASCO imagery at the start of the CME, but this backfilled with additional imagery. The source for this CME is an…

CME observed to the NW in SOHO LASCO C2/C3 and GOES CCOR-1, likely not observed in STEREO A COR2 either due to faintness or a data gap starting at 2026-09-14T18:53Z before it becomes visible. The source is far-sided…

- SOHO: LASCO/C2
Very faint CME with an unclear front seen to the NE in early images of SOHO LASCO C2 only. It is not seen in SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1, likely because of its faintness. No source for this feature has…

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, 06:59 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.
