Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-14T15:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-14T15:24:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME observed to the west in SOHO LASCO C2/C3 and GOES CCOR-1, and about 4 frames at the edge of STEREO A COR2's field-of-view after a brief data gap from 2025-05-14T12:23Z-T15:53Z. The source may be field line movement over the southwest limb observed starting around 2025-05-14T15:15Z in SDO AIA 171 and GOES SUVI 284.

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

Only two frames of STEREO A COR2 are usable, so running difference image quality is low, but it is enough to track the front and triangulate. 1: Result 1 (2.0 AU)
