- 741 km/s
This CME is visible to the east in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is a filament eruption spanning S12E15 to S20E30 which begins to lift off around 2026-10-12T04:45Z as seen in SDO…

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: 13 Oct 2026, 00:18 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.
