Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-21T12:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3

Source Location: S20W33
Active Region Number: 13638
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
GAP: Data gap
Source Signature Keyword:
FLR: Flare

Morphology Keyword:
L: Loop
Note: Narrow loop CME seen to the South/Southwest in SOHO LASCO C2/C3. Source likely small flare at 2024-04-21T12:16Z seen in GOES SUVI 304 and jet of material from S20W33 (near AR 3638) at 2024-04-21T12:19Z seen in GOES SUVI 304 and SDO AIA 304. Data gap in STEREO A COR2 lasting from 2024-04-21T11:38Z to 2024-04-22T02:23Z (with one frame timestamped 2024-04-2119:23Z). No STEREO A COR2 imagery was available for this CME.
