Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-12-28T23:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-12-28T23:00:00-CME-001 (version 3)
Source Location: N08W28
Active Region Number: 14317
Note Keyword:
DPL: CME exhibits dimpled front
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
L: Loop
Note: CME first seen to the West by SOHO LASCO C2 beginning at 202512-28T23:00Z, as well as by SOHO LASCO C3 and GOES CCOR-1 in later frames. This CME is not visible in STEREO A COR2 due to a data gap which began at 2025-12-28T17:53Z. The source of this event is an M4.2 flare from AR 4317 (N08W28) which peaked at 2025-12-28T22:39Z as seen in SDO AIA 131. A wide region of dimming stretching towards the South and West can be seen in SDO AIA 193 and 211, along with field line opening seen in SDO AIA 171 and GOES SUVI 284.

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 |
