Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-04-02T20:46Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-04-02T20:46:00-CME-001 (version 1)
Source Location: N12W15
Active Region Number: 14404
Note Keyword:
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption

Note: Second of a two-part CME associated with an M3.5-class solar flare in Active Region 14404 (N12W18) and subsequent filament eruption taking place between 2026-04-02T16:00Z and 21:00Z, the CME is narrow and seen to the northwest in SOHO LASCO C2, more northerly as compared with the earlier 2026-04-02T18:48Z CME but closely following behind it, and not yet seen in STEREO A COR2A due to a data gap. There is a filament eruption clearly seen after 19:30Z best seen in GOES SUVI 304 which is the likely source and suggests the eruption may have been deflected slightly to the north relative to the source.

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 |

Updated measurement using SOHO C2, C3 and GOES CCOR-1 which suggests the filament eruption CME is wider than previously thought--its width increases as it propagates outward into the field of view, especially in SOHO C2/C3. |
