SOHO: LASCO/C2

SOHO: LASCO/C3

Image Type: running difference
Speed (km/s): 342.0
Speed measured at height (Rs): 6.1
Type: S
Direction (LON/LAT in HEEQ): None Entered / 4.0

Note:

Plane of sky method chosen for this measurement due to the lack of clear source location. The CME's leading edge is not clearly visible in STEREO A COR2 imagery, and could not be measured with a best fit with SOHO in SWPC_CAT. The CME fades away quickly after early frames of C3 difference imagery.
