Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-12-28T09:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-12-28T09:12:00-CME-001 (version 1)
Source Location: S07W55
Active Region Number: 13933
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME seen to the NW in SOHO LASCO C2/C3 and STEREO COR2A, notably more faint in COR2A and barely visible in COR2A running difference imagery. The source for this CME is uncertain, as it appears to form early in the LASCO C2 FOV rather than moving out from the occulting disk, but there are two potential candidates if it does start on-disk. A small filament eruption from AR 3933 (~S07W55) starting at 2024-12-28T07:56Z in GOES SUVI 195/304 fits the measured longitude well but not latitude, and there is also field line movement beginning on the NW limb (~N18) around 2024-12-28T08:08Z in GOES SUVI 195 that doesn't fit longitude but is a more northward latitude. Both sources time well but are off on other parameters, AR 3933 is a closer match so it has been analyzed as the most likely.

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.

Triangulated measurement between SOHO LASCO C2/C3 and STEREO COR2A, noting the CME is much fainter in COR2A running difference than COR2A white light. Using the white light imagery as a reference, the CME was matched to the running difference within swpc_cat, allowing a good confidence triangualtion around W65. |
