Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-08-29T22:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-08-29T22:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
Morphology Keyword:
Note: CME first seen to the ESE in SOHO LASCO C2 starting at 2025-08-29T22:12Z. CME is also seen to the ESE in SOHO LASCO C3, STEREO A COR2, and GOES CCOR-1. The CME fades before leaving the FOV of C2 and is easier to see in running difference imagery. There is not a good, discernible source candidate for this CME on the Earth-facing disk, so the source is possibly 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 -84.0 -9.0 809.0 C 19.0 2025-08-30T02:09Z Measurement based on best-fit among SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. There is some uncertainty in this measurement due to the faintness of the front and lack of good source candidate. 1: Result 1 (2.0 AU)
Mars = 2025-09-03T12:00Z
2: Result 2 (5.5 AU)
Mars = 2025-09-03T12:00Z
Psyche = 2025-09-05T00:00Z
