Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-03-15T17:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-03-15T17:36:00-CME-001 (version 1)
Source Location: S40E60
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
L: Loop
Note: CME to the southeast in SOHO LASCO C2, C3, and STEREO A COR2. Source is the clear liftoff of material seen on the SE limb in SDO AIA 171 starting as early as 2024-03-15T15:30Z. Subtle dimming on the Earth-facing disk, centered at S40E60, can be seen in SDO AIA 193 at 2024-03-15T18:40Z. There is some field line movement seen on GOES SUVI 284 and 195 at the same time and location as this dimming. Small amount of ejecta seen on the SE limb in GOES SUVI 304 at 2024-03-15T18:30Z, which is long after the start time of this CME, however this is a prolonged and relatively slow CME.

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.

CME Analysis M2M_CATALOG LE true SWPC_CAT -57.0 -61.0 368.0 S 33.0 2024-03-16T07:19Z Candidate source location on the Earth-facing disk (dimming at S40E60) is very subtle, but using this candidate source location with southward deflection yields a better stereoscopic fit than using a longitude beyond the limb. Only two frames of STEREO A COR2 difference imagery were available for this CME due to a data gap which lasted from 2024-03-15T15:53Z to 2024-03-16T03:23Z in difference imagery.
