Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-29T19:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-29T19:00:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
O: Other
Note: A very faint CME with a faint fuzzy front to the NNW in SOHO LASCO C2, STEREO A COR2 and GOES CCOR-1 and mostly obscured by the pylon in C3, partially overlapping with the slower but brighter 2025-06-29T18:36Z CME. The front of this faint more northern CME is very difficult to trace because of its faintness in any coronagraph other than SOHO. No clear source was found for it, but it might also be connected with the prominent loop-like eruption of the northwestern filament that is happening on/behind the NW limb and which likely produced 2025-06-29T18:36Z CME.

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.
