Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-08-20T02:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2

Note: This CME is brightly visible to the SE in SOHO LASCO C2, C3, and STEREO A COR2 imagery. The source is not clear, but may be associated with faintly visible slow moving field lines along the SE limb in GOES SUVI 284 starting around 2024-08-19T23:00Z. There is a dimming visible on the disk to the NE of AR 13790 starting around 2024-08-20T00:40Z, however the directionality of the dimming does not correlate well with the directionality of the CME.

There are possibly overlapping features included in this analysis. The CME appears to speed up in later frames, so earlier frames were not included in this analysis. 1: Result 1 (2.0 AU)
