Detecting Instruments:

SOHO: LASCO/C2

Image Type: running difference
Speed (km/s): 537.0
Speed measured at height (Rs): 6.8
Type: C
Direction (LON/LAT in HEEQ): 90.0/ -44.0
Half Angular Width (degree): 10.0

Time@21.5: 2026-02-11T02:06Z
Info/Session URL: None Entered
Note:

Parameters based on potential source location area and best fit in SOHO LASCO C2 imagery. This is specifically measuring the most narrow portion of the feature visible in difference imagery. There is a much slower, slightly wider portion that may also be associated with this source that measured with speeds below 150 km/s. The longitude of this CME may vary by +/- 10 degrees due to limited stereoscopic viewpoints of the source location.
