Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-21T00:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-04-21T00:48:00-CME-001 (version 1)
Source Location: S18W21
Active Region Number: 13638
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
J: Jet
Note: Faint CME to the south-southwest in SOHO LASCO C2, C3, and after a data gap in STEREO A COR2 imagery. The source is likely from AR3638 (S18W21) but could also possibly be from AR3637 (S15W26) as there are multiple ejecta eruptions from both regions in the hours ahead of the first timestamp for which this CME is visible.
