Start Time: 2025-09-05T06:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2

Activity ID: 2025-09-05T06:48:00-CME-001 (version 3)
Source Location: N20E20
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
O: Other
Note: CME seen to the NE in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. Source is a broad area of brightening, dimming, and subtle opening field lines seen from an area spanning between AR 14207 (N29E07) and AR 14210 (N08E24), centered at N20E20, seen at 2025-09-05T05:00Z in SDO AIA 193/171. Opening field lines from this broad area can be seen very well in STEREO A EUVI 195 at 2025-09-05T05:25Z.

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
