Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-06T04:09Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-03-06T04:09:00-CME-001 (version 1)
Source Location: S25E30
Note Keyword:
DFL: Likely deflection of the event within the FOV
DPL: CME exhibits dimpled front
GAP: Data gap
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
O: Other
Note: CME observed to the SE in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. A GOES CCOR-1 eclipse briefly obscures early frames of the CME, and the LASCO C3 pylon obscures analysis in running difference imagery. The source is a small filament eruption centered around S25E30 starting around 2026-03-06T02:32Z in GOES SUVI 304, also observed as some brightening and field line movement in GOES SUVI 171/195/284/304 and some dimming in GOES SUVI 171/195.

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 |

Triangulation between SOHO LASCO C2, STEREO A COR2, and GOES CCOR-1. LASCO C3 pylon obscures the front in running difference imagery. The CME front is dimpled and somewhat diffuse, so this analysis encompasses as much of the bright material as possible. |
