Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-03-21T18:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2024-03-21T18:48:00-CME-001 (version 2)
Source Location: N30E30
Active Region Number: 13614
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: This CME is visible to the northeast in SOHO LASCO imagery, but is not seen in STEREO A COR2 because of a nighttime data gap. The source is one (or two simultaneous) filament eruption(s) near Active Region 3614 (~N30E30) starting around 2024-03-21T18:00Z as seen in SDO AIA 131, 171, 193, 304 imagery. An opening of field lines is visible at this time in SDO AIA 171 and 193 as well, with post eruptive dimming visible further north around 19:00Z in SDO AIA 193. The filament stretches from -40 to -5 degrees longtitude and there is some uncertainty about its latitude also because the dimming is further north from post-eruptive arcades.

Parameters are uncertain because longitude could range from -45 to -10 degrees and latitude - from 25 to 50 degrees. 1: Result 1 (2.0 AU)
