Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-21T02:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-02-21T02:24:00-CME-001 (version 1)
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
LS: Loop and Shock Candidate
U: Unknown
Note: Bright CME to the SE in SOHO LASCO C2/C3 and STEREO A COR2. Source is just beyond the SE limb at an apparent latitude of S42. The source location in UV imagery matches well with an estimated location of old Active Region 13575 (S37, estimated Lon: E95). Surge of ejecta seen in SDO AIA 171 around 2024-02-21T02:00Z and bright ejecta in SDO AIA 304 starting at 2024-02-21T01:54Z, both originating from just beyond the SE limb. This CME overlaps heavily with CME:2024-02-21T02:12Z, which also originated just beyond the SE limb.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

Measurement of the bulk using estimate of source location with southward deflection as seen in UV imagery and best fit between coronagraphs. Leading edge is only visible for 3 frames in STEREO A COR2 running difference imagery due to a data gap lasting from 2024-02-20T13:53Z to 2024-02-21T03:23Z. |
