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 5)
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: The front of this CME is visible as a partial halo to the northwest, closely following the front of the 2024-03-23T01:25Z halo CME immediately preceding this CME and associated with the X-class flare. The faint shock front of this CME is visible to the southwest in SOHO LASCO C2/C3 imagery. The start of this CME is covered by a data gap in STEREO A COR2 from 2024-03-22T18:23Z to 2024-03-23T03:23Z, but its front is seen after this data gap in several frames of COR2 coronagraph before exiting the field of view of COR2. The likely source of this follow-up CME is an eruption following the initial flare which is characterized by a slowly developing dimming to the SSW of Active Region 3614 (N25E07) and an EUV wave and deep northern dimming to the NE of this Active Region. Alternatively, the source of this CME could be the unspecified flare from Active Region 3615 (S14E15) sympathetic to the X-class flare. The intensity of the flare from Active Region 3615 could not be measured as it it was concurrent with the X-flare (so this more minor flare is not in this database).

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. |
