Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-11T17:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-11T17:36:00-CME-001 (version 1)
Source Location: N18W50
Active Region Number: 14058
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Faint and wide loop CME visible to the NW in SOHO LASCO C2. Source is field line movement and gradual dimming seen from AR 4058 (N18W50) and AR 4055 (N08W45), as well as field line movement seen on the NW limb, starting at 2025-04-11T16:33Z in SDO AIA 171. No STEREO A COR2 imagery was available in real time for this CME due to a data gap which began at 2025-04-11T11:23Z.
