Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-11T07:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-04-11T07:00:00-CME-001 (version 1)
Source Location: N20E10
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
U: Unknown
Note: Faint CME visible to the NE in SOHO LASCO C2/C3 and STEREO A COR2. The start time is unclear due to the CME's faintness. The candidate source is a filament eruption centered around N20E10, with liftoff starting around 2024-04-11T05:48Z in SDO AIA 304. The filament can be seen deflecting to the east. The eruption is also best seen as dimming in SDO AIA 193. STEREO A EUV 195/304 also observes the eruption.

CME Analysis M2M_CATALOG LE true SWPC_CAT -31.0 6.0 911.0 C 20.0 2024-04-11T10:18Z Measurement based on the best fit between SOHO LASCO C3 and STEREO A COR2 imagery. This event has a diffuse leading edge, which is difficult to measure in later imagery, and exhibits an eastern deflection from the source location. Multiple measurements produced longitudes ranging from -26 to -31 degrees and speeds ranging from 756 to 1064 km/s. 1: Result 1 (2.0 AU)
