Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-19T00:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-19T00:00:00-CME-001 (version 1)
Source Location: N50E10
Note Keyword:
DPL: CME exhibits dimpled front
Ha: Bright emission (likely H-alpha emission)
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: Large, bright CME first seen in the NW by SOHO LASCO C2 beginning at 2025-05-19T00:00Z as well as by SOHO LASCO C3, STEREO A COR2, and GOES CCOR-1 in later frames. The source of this event is a large filament eruption centered at approximately N50E10 with a gradual liftoff beginning at approximately 2025-05-18T19:00Z. This filament can be seen exhibiting some Northwestern deflection in SDO AIA and GOES SUVI 304, along with dimming visible in SDO AIA 193 and 211, field line opening visible in SDO AIA 171 and post eruptive arcades visible in SDO AIA 131 and 193.

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 |
