Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-17T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-04-17T21:12:00-CME-001 (version 1)
Source Location: S18E20
Active Region Number: 13638
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
GAP: Data gap
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
O: Other
Note: Faint filament eruption to the SE seen in SOHO LASCO C2 and a few frames of C3. The source is a filament eruption starting at 2024-04-17T20:04Z from AR 3638, best observed in SDO AIA 304 and GOES SUVI 304 as outflowing dark material, deflecting southeastward as it travels. This eruption is paired with very a impulsive double peaked C9.0 and C9.7 flare best seen in SDO AIA 131. Slight dimming and field line movement observed in SDO AIA 171/193/211 as well.

CME Analysis M2M_CATALOG LE true SWPC_CAT -21.0 -20.0 378.0 S 28.0 2024-04-18T05:27Z Measurement made using the EUV-observed source at S18E20 as a basis and finding a good fit nearby. Only using SOHO LASCO C2 and the few available C3 frames due to faintness of the front, and lack of usable STEREO COR2A frames due to a data gap. 1: Result 1 (2.0 AU)
