Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-02-16T12:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-02-16T12:12:00-CME-001 (version 1)
Source Location: N20W60
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
L: Loop
Note: Faint CME seen to the NW in SOHO LASCO C2/C3. This CME is completely covered by a data gap in STEREO A COR2 which lasted from 2025-02-16T11:38Z to 2025-02-16T15:23Z. Source is the partial liftoff of a filament seen starting as early as 2025-02-16T10:48Z in SDO AIA 304 and in GOES SUVI 304/284 as brightening and departure of some filamentary material and opening of surrounding field lines. Filament spans from N00W40, arcs up to N20W60, then arcs down slightly to N10W70, as seen in SDO AIA 304 at 2025-02-16T10:48Z.

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.

CME Analysis M2M_CATALOG LE true SWPC_CAT 61.0 32.0 394.0 S 22.0 2025-02-16T21:09Z Best fit measurement using candidate source location, several SOHO LASCO C2 frames, and two frames of SOHO LASCO C3. The leading edge is narrow and for most frames is completely obstructed by the pylon in SOHO LASCO C3. This CME is completely covered by a data gap in STEREO A COR2 which lasted from 2025-02-16T11:38Z to 2025-02-16T15:23Z. Not modeled Hannah Hermann on 2025-02-16T20:45Z
