Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-18T20:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-02-18T20:36:00-CME-001 (version 1)
Source Location: S07E60
Note Keyword:
DFL: Likely deflection of the event within the FOV
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME first seen to the East by SOHO LASCO C2 beginning at 2026-02-18T20:36Z, as well as by SOHO LASCO C3 and GOES CCOR-1 in later frames. This event is not visible in STEREO A COR2 due to a data gap which began at 2026-02-18T15:53Z. The source of this event is a long duration C2.2 flare located as approx. (S07E60) which peaked at 2026-02-18T20:42 as seen in GOES SUVI 131. Field line opening is also visible in GOES SUVI 171 and 193 exhibiting a possible Northern deflection. This CME partially overlaps with CME: 2026-02-18T21:00Z.

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 |
