Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-22T21:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-04-22T21:48:00-CME-001 (version 1)
Source Location: S20W51
Active Region Number: 13638
Note Keyword:
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is visible to the south/southwest in SOHO LASCO C2/C3 and STEREO A COR2 imagery for a few frames before becoming too faint to observe. The source is an eruption and subsequent M1.5 flare near AR 3638 (S20W51) starting around 2024-04-22T21:18Z as seen in SDO AIA 131, 171, 193, 304 imagery. Faint field line movement is visible over the SW limb in SDO AIA 171 and 193 imagery at this time as well. This event partially overlaps with CME: 2024-04-22T22:24Z.

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. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type

CME Analysis M2M_CATALOG LE true SWPC_CAT 51.0 -59.0 661.0 C 25.0 2024-04-23T02:56Z Measurement based on the best fit between SOHO LASCO C2 and STEREO A COR2 imagery. The longitude is based on the source location but the source eruption exhibits a clear southern deflection. This matches the southern latitude corresponding to the best fit between coronagraphs.
