Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-16T09:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2025-02-16T09:12:00-CME-001 (version 1)
Source Location: N27E30
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
L: Loop
Note: Faint loop CME seen to the S in SOHO LASCO C2 and the SE in STEREO A COR2. The leading edge is too diffuse to discern in SOHO LASCO C3. Source is a small eruption from N27E30: a narrow set of opening field lines from the location is seen in GOES SUVI 284 at 2025-02-16T07:45Z as well as post-eruptive brightening seen in SDO AIA 304 at 08:25Z, followed immediately by a much wider and fainter set of opening field lines which extends across the southern hemisphere of the disk all the way to roughly near AR 13994 (S20W22).

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.
