Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-17T03:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-02-17T03:24:00-CME-001 (version 1)
Source Location: N50W10
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
BR: Brightening
Morphology Keyword:
L: Loop
Note: Extremely faint loop CME visible to the N in SOHO LASCO C2. The leading edge is not discernable in SOHO LASCO C3 or in STEREO A COR2. Source is subtle brightening and field line movement at N50 and spanning W00-W20, just north of a coronal hole, seen in SDO AIA 193 and GOES SUVI 284 lasting between 2025-02-17T01:40Z-02:50Z.

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 -4.0 63.0 400.0 S 33.0 2025-02-17T12:14Z Measurement based on source location and best fit in SOHO LASCO C2. Latitude matches well, but longitude is measuring slightly east of source location; there may have been deflection due to the nearby coronal hole observed in UV imagery.
