There is also a wider, more northern portion that is not visible by the time the CME makes it into SOHO LASCO C3. Because the extra feature is not visible later in SOHO LASCO C3, the bright bulk has been prioritized for the measurement. The extra, wider feature is more prominent in GOES CCOR-1, but it is still not as bright as the main bulk. The approximate longitude of the filament footpoints is around E60 to E80. Since a triangulated measurement cannot be made as there is no STEREO A COR2 imagery for this event, a starting point of E60 was used for this measurement. Because of this, there will inherently be a greater than normal degree of uncertainty associated with this measurement.","associatedCMELink":"https://webtools.ccmc.gsfc.nasa.gov/DONKI/view/CME/43706/-1","catalog":"M2M_CATALOG","featureCode":"LE","dataLevel":"0","measurementTechnique":"SWPC_CAT","imageType":"running difference","tilt":null,"minorHalfWidth":null,"speedMeasuredAtHeight":null,"submissionTime":"2026-01-01T15:36Z","versionId":1,"link":"https://webtools.ccmc.gsfc.nasa.gov/DONKI/view/CMEAnalysis/43707/-1"},{"time21_5":"2026-01-02T01:01Z","latitude":22.0,"longitude":-9.0,"halfAngle":35.0,"speed":628.0,"type":"C","isMostAccurate":true,"associatedCMEID":"2026-01-01T19:36:00-CME-001","associatedCMEstartTime":"2026-01-01T19:36Z","note":"BULK measurement based on approximate source location and best fit in SOHO LASCO C2/C3 and GOES CCOR-1.","associatedCMELink":"https://webtools.ccmc.gsfc.nasa.gov/DONKI/view/CME/43719/-1","catalog":"M2M_CATALOG","featureCode":"LE","dataLevel":"0","measurementTechnique":"SWPC_CAT","imageType":"running difference","tilt":null,"minorHalfWidth":null,"speedMeasuredAtHeight":null,"submissionTime":"2026-01-01T22:19Z","versionId":1,"link":"https://webtools.ccmc.gsfc.nasa.gov/DONKI/view/CMEAnalysis/43720/-1"},{"time21_5":"2026-01-02T01:09Z","latitude":23.0,"longitude":-16.0,"halfAngle":43.0,"speed":585.0,"type":"C","isMostAccurate":true,"associatedCMEID":"2026-01-01T19:36:00-CME-001","associatedCMEstartTime":"2026-01-01T19:36Z","note":"SHOCK measurement based on approximate source location and best fit in SOHO LASCO C2/C3 and GOES CCOR-1.","associatedCMELink":"https://webtools.ccmc.gsfc.nasa.gov/DONKI/view/CME/43719/-1","catalog":"M2M_CATALOG","featureCode":"SH","dataLevel":"0","measurementTechnique":"SWPC_CAT","imageType":"running difference","tilt":null,"minorHalfWidth":null,"speedMeasuredAtHeight":null,"submissionTime":"2026-01-01T22:20Z","versionId":2,"link":"https://webtools.ccmc.gsfc.nasa.gov/DONKI/view/CMEAnalysis/43721/-1"},{"time21_5":"2026-01-02T11:17Z","latitude":49.0,"longitude":90.0,"halfAngle":25.0,"speed":322.0,"type":"S","isMostAccurate":true,"associatedCMEID":"2026-01-01T23:12:00-CME-001","associatedCMEstartTime":"2026-01-01T23:12Z","note":"Approximate analysis based on the fit with all three coronagraphs (SOHO LASCO C2/C3, STEREO A COR2 and GOES CCOR-1).
