Note: CME first visible to the S in SOHO LASCO C2 starting at 2025-04-14T18:12Z in white light. CME is visible starting a few frames earlier at 2025-04-14T17:36Z in running difference imagery. This CME is also seen to the S in SOHO LASCO C3 but is partially obscured by the pylon. The source of this CME is possibly far-sided. There is not a good source candidate on the Earth-facing disk, but there is some very faint field line movement from on or beyond the S limb best seen in SDO AIA 171 beginning around 2025-04-14T15:42Z. The faint field line movement can also be seen in GOES SUVI 284. Another less likely source candidate is some minor movement starting around 2025-04-14T16:39Z best seen in SDO AIA 193 about S20E10.

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 |

Plane-of-sky measurement based on running difference imagery from SOHO LASCO C2. CME is partially visible in C3 but is too obscured by the the pylon to get a good measurement. Plane-of-sky measurement chosen due to lack of definitive source candidate. |
