CME Analysis Information (for CME activity ID: 2024-02-21T16:12:00-CME-001)
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

Image Type: running difference
Speed (km/s): 880.0
Speed measured at height (Rs): None Entered
Type: C
Direction (LON/LAT in HEEQ): -90.0/ -61.0
Half Angular Width (degree): 31.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2024-02-21T20:12Z
Info/Session URL: None Entered
Note:

Approximate measurement of the narrower brighter bulk of the CME based on swpc_cat analysis with one coronagraph (SOHO) as STEREO has a data gap since 2024-02-21T13:23Z. Since the source is not seen (behind the limb), the longitude could possibly be a little higher (maybe up to -100 degrees), but we are using the approximate longitude of old returning AR 3575 as the likely longitude.
