Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-05T03:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-05T03:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
Morphology Keyword:
OS: Other and Shock Candidate
Note: A faint CME with a fuzzy front to the northeast, closely followed by a second, brighter, front, better seen in SOHO than in STEREO A COR2 coronagraph. There is a super faint wider front that might indicate a shock front. No source has been found for this CME, so it is likely far-sided.

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 -121.0 14.0 641.0 C 24.0 2025-03-05T08:49Z A very approximate analysis based on the fit with two coronagraphs. The front is very unclear/fuzzy in STEREO A COR2 and no source has been found for this event, so this analysis is very uncertain. 1: Result 1 (2.0 AU)
OSIRIS-APEX = 2025-03-07T06:27Z
2: Result 2 (5.5 AU)
OSIRIS-APEX = 2025-03-07T06:09Z
