Coronal Mass Ejection
Catalog: M2M_CATALOG

All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2

SUR: Surge-like eruption
Source Signature Keyword:
FLR: Flare
DFLR: Double ribbon flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
F: Flux Rope
FS: Flux Rope and Shock Candidate
Note: First of two CMEs seen to the N and W in SOHO/STEREO A imagery in association with a long duration M1.9-class flare near the vicinity of AR13386 (N12W46) and a complex, sympathetic eruptive signature before/after the flare. This CME is directed more northward than the latter CME, appearing bulbous with a protruding leading edge and a wide/faint shock seen predominantly to the N and NE. The eruptive signature is characterized by an erupting/disappearing loop starting around 04:04Z seen best in SDO 171 occurring before the M1.9-class flare as well as opening magnetic field lines off the western limb. SDO 304 shows a near-simultaneous filamentary surge north of the flaring Active Region 3386 and south and east, towards the direction of the observing spacecraft, starting around 03:55Z, followed by a minor sympathetic filament liftoff closer to 05:30Z. SDO 193 shows three distinct areas of dimming: NW and SE of the active region during and occurring with the flare, then sympathetic dimming N and E of the AR in association with the northern filament surge.

If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME |
