Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-29T18:36Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

GOES: CCOR-1

Activity ID: 2025-06-29T18:36:00-CME-001 (version 1)
Source Location: N35W90

Note Keyword:

3P: 3-part structure CME

FOV: Front Bright front; may be evidence of pileup

OFL: Outflowing material at the back of the CME

OVR: Event partially overlaps with another CME

Source Signature Keyword:

FIL: Filament eruption

OFL: Moving/Opening field lines

BR: Brightening

DIM: Dimming

Morphology Keyword:

F: Flux Rope

Note: Bright slow lightbulb CME seen to the northwest in SOHO LASCO C2, STEREO A COR2 and GOES CCOR-1 and partially obscured by the pylon in C3. Its source is a slowly developing high northern latitude filament eruption, best seen as a giant loop centered around ~N35W50 (as seen from Stereo A) in EUVI A 304; its clearest view is at 2025-06-29T18:15Z (but it starts lifting off much earlier).
