Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-19T14:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-05-19T14:23:00-CME-001 (version 1)
Source Location: S10E35
Active Region Number: 13685
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
O: Other
Note: Thin, faint CME seen to the east in all coronagraphs. The source is not too clear, but may be associated with an M1.9 flare from AR 3685 that peaked at 2024-05-19T13:44Z, best observed in SDO AIA 131. Some weak field line movement is observed at this time of the flare in SDO AIA 171/193, and dark filamentary material is seen rising along field lines after the flare occurs and correlates to the start time of the CME in coronagraph imagery.

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 SWPC_CAT -35.0 -6.0 524.0 C 14.0 2024-05-19T20:40Z Triangulated measurement between SOHO LASCO and STEREO COR2A using AR 3685 as an initial source, finding a good nearby fit. In the already low amount of available imagery, the front is notably faint and blurry, which made for difficulty tracking the leading edge. 1: Result 1 (2.0 AU)
