Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-14T11:01Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-03-14T11:01:00-CME-001 (version 2)
Source Location: N12W90
Active Region Number: 14384
Note Keyword:
GAP: Data gap
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: CME observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and in limited STEREO A COR2 imagery. The source is a filament eruption and field line movement from AR 14384 observed on the west limb, around N12W90, in GOES SUVI 171/195/284/304 starting around 2026-03-14T10:21Z.

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.

CME Analysis M2M_CATALOG LE true SWPC_CAT 106.0 19.0 407.0 S 21.0 2026-03-14T19:30Z Triangulation between SOHO LASCO C2/C3 and limited and poor quality STEREO A COR2 imagery. The source longitude could vary E90-E110. The CME shape is quite dimpled, so the best fit here encompasses the full width of the material while the leading most edge is on the southern piece of the fit. 1: Result 1 (2.0 AU)
