CME Analysis Information (for CME activity ID: 2026-04-02T20:46:00-CME-001)
Measurement Creation Time: 2026-04-02T23:37Z
Catalog: M2M_CATALOG
Data Level: 0 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis)
Use as primary measurement: true
Measurement Technique: SWPC_CAT

Detecting Instruments:

SOHO: LASCO/C2

SOHO: LASCO/C3

GOES: CCOR-1

Image Type: running difference
Speed (km/s): 832.0
Speed measured at height (Rs): 16.0
Type: C
Direction (LON/LAT in HEEQ): 15.0/ 20.0

Info/Session URL: None Entered
Note:

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.
