Note: Faint, wide, multi-front streamer blowout CME seen to the NW in SOHO LASCO C2/C3. A data gap in STEREO A COR2 from 2025-02-21T15:53Z to 2025-02-22T03:23Z completely covers this CME. The source is not discernable on the Earth-facing disk and is likely farsided.

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 using several frames of SOHO LASCO C2 and C3. Tricky to track the same leading edge between C2 and C3, since there are several slow loops that emerge in C2 and eventually merge into one brighter loop by the time C3's field of view is reached. There is also a data gap in STEREO A COR2 from 2025-02-21T15:53Z to 2025-02-22T03:23Z which completely covers this CME. |
