Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-08T21:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-08T21:48:00-CME-001 (version 1)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: CME first seen to the W in SOHO LASCO C2 starting at 2025-06-08T21:48Z. CME also seen to the W in SOHO LASCO C3, GOES CCOR-1, and STEREO A COR2. There is likely some deflection early in the propagation into the FOV of SOHO LASCO C2. The source of this CME is likely a loop seen rising from beyond the W limb and some moving field lines best seen in SDO AIA 171 beginning around 2025-06-08T20:27Z.

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 131.0 -5.0 491.0 S 17.0 2025-06-09T05:10Z Measurement based on triangulation between SOHO LASCO C2/C3 and STEREO A COR2 as well as visible source beyond the W limb. The couple of visible frames in COR2A help with triangulation, but the front itself is not defined enough to be used in the measurement. 1: Result 1 (2.0 AU)
