Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-28T08:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2024-04-28T08:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: This faint CME is visible to the NW in SOHO LASCO C2 white light and difference imagery, and extremely faintly in C3 white light imagery. Not visible in STEREO A COR2 due to faintness. The source is uncertain, but one candidate is a set of very slowly rising loops just beyond the NW limb at N40 seen rising starting as early as 2024-04-28T03:20Z in SDO AIA 171 but not leaving SDO AIA's field of view until about 2024-04-28T05:00Z. Small amounts of bright material seen moving on the NW limb, possibly falling back to the solar surface, in SDO AIA 304 at 2024-04-28T03:30Z.
