Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-11T13:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-04-11T13:48:00-CME-001 (version 1)
Source Location: N08W43
Active Region Number: 14055
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
J: Jet
Note: Extremely faint and narrow CME seen to the SW in SOHO LASCO C2. The leading edge becomes diffuse before leaving the C2 field of view. Source is unclear, but there is continual flickering and field line movement from AR 4055 (N08W43), including a small instance of southward directed field line movement seen starting at 2025-04-11T12:45Z 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.

Measurement of the faint leading edge using four frames of SOHO LASCO C2. Measurement was made using the candidate source longitude, taking into consideration the heavy southern deflection which was possibly indicated in UV imagery. The leading edge becomes diffuse before leaving the C2 field of view. 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. |
