Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-11T21:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-11T21:48:00-CME-001 (version 1)
Source Location: N35E80
Note Keyword:
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Wide loop CME visible to the NE in SOHO LASCO C2. Source is an eruption near the NE limb, seen as a rising loop of opening field lines starting at 2025-04-11T20:40Z in SDO AIA 171. There are two connected rising loops seen on the E limb, which lift off together in the same eruption. One spans from approx. N22 to N30 along E70, while the other spans from approx. N35 to N50 along E90. 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.
