Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-04T16:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-04T16:36:00-CME-001 (version 1)
Source Location: N30W92
Note Keyword:
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
L: Loop
Note: CME seen to the N in SOHO LASCO C2 and to the N in STEREO A COR2. Source is a filament eruption from just beyond the NW limb. A prominence from just beyond the limb can be seen beginning to liftoff starting at 2025-04-04T16:08Z in GOES SUVI 304. Opening field lines seen in GOES SUVI 284 and ejecta seen in GOES SUVI 304 both show strong northern deflection of this eruption, with ejecta traveling nearly due north. STEREO A EUVI 195 and 304 show that the prominence was centered at about N30 and spanned from W82-W92 (in SDO coordinates).

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.

Strong northern deflection was visible from the source location seen in UV imagery from SDO AIA, STEREO A EUVI, and GOES SUVI, which is reflected in the best fit parameters.
