Note: Visible in the W of SOHO LASCO/C2; STEREO A data gap during real-time has since backfilled. Associated with an eruption from AR 12898, rising field lines visible in SDO AIA 171/193 beginning 2021-12-05T07:03Z, material outflow visible in SDO AIA 304 around 2021-12-05T07:07Z. Associated with M1.4 flare peaking 2021-12-05T07:19Z. Significant northward deflection from source location in SDO FOV.

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 |
