Note: The CME start time is actually 2025-07-09T13:25Z (4 hours earlier than the start time in DONKI). This is because SOHO LASCO was not available on the day when the CME was analyzed and entered into DONKI. CME with a flux rope clearly seen in coronagraphs, first seen to the NW in GOES CCOR-1 starting around 2025-07-09T17:30Z. CME is also seen to the N in STEREO A COR2. CME was originally covered by a data gap in SOHO LASCO C2/C3, but LASCO eventually backfilled. A possible source for this CME is a filament eruption starting to the SW of AR 14137 beginning around 2025-07-09T15:30Z and moving eastward - faint ejecta can be seen leaving the disk in SDO AIA 304. If this candidate is the source of the CME, there is some significant deflection to the NW.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

Approximate analysis based on the fit of the faint front with three coronagraphs. There seems to be a significant northwestern deflection happening when comparing the latitude and longitude of the CME with the approximate location of the source - a filament eruption centered around (N12W15). |

Measurement based on best-fit between GOES CCOR-1 and STEREO A COR2. This CME is covered by a data gap in SOHO LASCO C2/C3. There is a significant degree of uncertainty in this measurement due to poor quality running difference imagery. The half-width in particular is likely an overestimate. |
