- N16W105
- CME speed (most accurate analysis)
- 368 km/s
CME observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is former AR 14547 (~N15W105) as directly observed by STEREO A around the west limb from SDO. Observed across SDO AIA…

Outflow first seen to the NW in SOHO LASCO C2 starting around 2026-10-11T09:12Z. This feature is much easier to see later in its propagation into SOHO LASCO C3, GOES CCOR-1, and STEREO A COR2. The source is most likely…

- 618 km/s
This CME is visible to the east in GOES CCOR-1 and SOHO LASCO C2/C3 imagery. This event is seen in STEREO A COR2, directed towards the east, after it has exceeded the field of view due to a data gap from…

- CME speed (most accurate analysis)
- 457 km/s
This CME is visible to the southwest in GOES CCOR-1 and SOHO LASCO C2/C3 imagery. This event is not seen in STEREO A COR2 in real-time due to a data gap starting at 2026-10-11T17:38Z. The source may be related to…

- S16E23
- CME speed (most accurate analysis)
- 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…

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, 02:18 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.
