CME Analysis Information (for CME activity ID: 2026-06-18T13:23:00-CME-001)
Measurement Creation Time: 2026-06-18T17:04Z
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:

STEREO A: SECCHI/COR2

Image Type: running difference
Speed (km/s): 592.0
Speed measured at height (Rs): 8.1
Type: C
Direction (LON/LAT in HEEQ): 140.0/ -18.0
