Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-07-04T12:12Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2025-07-04T12:12:00-CME-001 (version 1)

Note Keyword:

SB: Streamer Blowout following CME

Source Signature Keyword:

Morphology Keyword:

Note: Slowly developing streamer with large and bright lobe seen to the southeast in SOHO LASCO C2/C3, GOES CCOR, and STEREO A COR2 seemingly associated with moving field lines far off the southeast limb of the Earth facing disk seen best in GOES SUVI 284 apparently on the front-side after triangulation but fairly far out of the ecliptic.
