CME Analysis Information (for CME activity ID: 2026-04-30T18:24:00-CME-001)
Measurement Creation Time:
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
STEREO A: SECCHI/COR2
Image Type: running difference
Speed (km/s): 237.0
Speed measured at height (Rs): 8.0
Type: S
Direction (LON/LAT in HEEQ): 6.0/ -20.0
Half Angular Width (degree): 32.0
Minor Half-width (degree): None Entered

Time@21.5: 2026-05-01T07:23Z
Info/Session URL: None Entered
Note: 
Measurement of the leading edge using SOHO C2 and STEREO A COR2 for triangulation, which suggests a front-sided source possibly associated with AR 4428. Appears to be more northward than the earlier CME occurring before it, though of very similar velocity.
