Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-07-29T17:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-07-29T17:48:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME observed to the WSW in SOHO LASCO C2/C3 and GOES CCOR-1, not in STEREO COR2A due to a data gap beginning at 2025-07-29T17:38. The source for this CME could be field line movement over the west limb observed in GOES SUVI 284 around 2025-07-29T16:05Z, which appears to trace back near the limb or far-sided.
