Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-26T18:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-04-26T18:00:00-CME-001 (version 1)

Note: This CME is visible to the northwest in SOHO LASCO C2/C3, but is not seen in STEREO A COR2 imagery due to a data gap. The source is likely far-sided, with faint field line movement visible over the northwest limb in GOES SUVI 171 starting around 2024-04-26T17:15Z. It is difficult to determine a possible longitude corresponding to this field line movement as the source is likely beyond the limb.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.

CME Analysis M2M_CATALOG LE true Plane-of-sky NONE 59.0 359.0 S 42.0 2024-04-27T03:28Z Due to a data gap in STEREO A COR2 imagery, there is no stereoscopic viewpoint available for this measurement. A plane-of-sky measurement was made using a longitude of 90 degrees as a result. Multiple measurements were attempted using estimated locations of former Active Regions which rotated off the disk, but none produced a reasonable fit.
