Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-11T10:08Z ( STEREO A: SECCHI/COR2 )

All Detecting Spacecrafts:

STEREO A: SECCHI/COR2

Activity ID: 2026-02-11T10:08:00-CME-001 (version 1)
Source Location: N17W128
Active Region Number: 14358

Note Keyword:

Source Signature Keyword:

OFL: Moving/Opening field lines

Morphology Keyword:

Note: This CME is visible to the northwest in STEREO A COR2 imagery. The source may be related to an eruption from former Active Region 14358, which was located at approximately N17W128 based on the rate of solar rotation, starting around 2026-02-11T09:15Z seen in STEREO A EUVI 195/304 imagery. A subsequent opening of field lines is visible over the northwest limb in STEREO A EUVI 195 imagery at this time as well.

As this event is not visible in SOHO LASCO C2/C3 or GOES CCOR-1 coronagraphs, a triangulated measurement was not available for this event. The measured parameters may vary slightly as a result.	1: Result 1 (2.0 AU) Juice = 2026-02-17T10:00Z		Mattie Anastopulos on 2026-02-11T13:47Z
