Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-03-23T01:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-03-23T01:48:00-CME-001 (version 3)
Active Region Number: 13615
Note Keyword:
COL: Possible collision with previous CME
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
HAL: Halo CME
OVR: Event partially overlaps with another CME
SEP: Solar Energetic Particle event
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
DIM: Dimming
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: This CME is visible as a partial halo to the northwest following the front of the earlier CME, with a fainter shock front portion visible to the southwest in SOHO LASCO C2/C3 imagery. There is a data gap in STEREO A COR2 from 2024-03-22T18:23Z to 2024-03-23T03:23Z, after which the end of this event is seen for a few frames before exiting the field of view but it overlaps in coronagraphs with the previous CME. The possible source the slower developing dimming to the SSW of Active Region 3614 (N25E07) following the initial X1.1 class flare, EUV wave and deep northern dimming to the NE of this Active Region. Alternative source is the concurrent flare from Active Region 3615 (S14E15). This event likely with CME: 2024-03-23T01:25Z.

Analysis of the second (after the X-class flare) bright front first seen to the north in SOHO LASCO C2 coronagraph, which is likely the bulk of the CME. This analysis is based on the best fit in two coronagraphs. Note that only two timestamps with this front are available from STEREO A COR2 because of a data gap. This bright front is also accompanied by a more diffuse, faint likely shock front further southeast, which is analyzed separately. |

Approximate analysis of the fainter, more SW, likely shock front of this CME. Analysis is based on the best fit in two coronagraphs, with two timestamps available in STEREO A COR2. We are using default half width of 45 degrees, adding to the uncertainty of this analysis. |
