L: Loop
Note: Very faint and slow CME seen to the southwest in SOHO LASCO C3 after a data gap, with the start time likely before 2025-03-26T23:42Z. The start of this CME is covered by data gaps in SOHO and STEREO A. In SOHO LASCO C2 the front has already exited its FOV at the end of the data gap at 2025-03-27T00:01Z. The CME front is not discernible in STEREO A COR2 at all after the data gap ending at 2025-03-27T03:23Z because of its faintness. No clear source has been found for this event in the EUV imagery.

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

CME Analysis M2M_CATALOG LE true Plane-of-sky NONE -2.0 326.0 S 25.0 2025-03-27T07:40Z The CME is not seen in STEREO A COR2 imagery because of the nighttime data gap. No source has been found for it, so it is likely behind the limb. Only plane-of-sky measurement is possible. Not modeled Anna Chulaki on 2025-03-27T16:08Z
