CME visible to the east in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely beyond the east limb, as moving/opening field lines are seen in SDO AIA 171 in ISWA as early as 2026-10-16T10:28Z.

Bright CME seen to the NW in SOHO LASCO C2/C3 and to the NW in STEREO A COR2. Its source is likely a messy eruption seen in the NW quadrant in STEREO A EUV 195/304 and centered very approximately around N12W140 near…

- SOHO: LASCO/C2
Faint and narrow CME seen to the E in early SOHO LASCO C2 imagery and not seen in C3, GOES CCOR-1 and STEREO A COR2 imagery, likely because of its faintness. The start time is likely at least an hour earlier but the CME…

Narrow CME/outflow to the E seen in SOHO LASCO C2/C3 and GOES CCOR-1. The CME is not seen in STEREO A COR2 imagery, which is available. No clear source was found in EUV imagery, so the CME is possibly far-sided.

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: 17 Oct 2026, 23:10 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.
