Note: This CME is visible in the east of SOHO LASCO C2 and C3. STEREO A COR2 data is not available. It is associated with a C4.4 flare from AR 12909 (S19E11) which peaked at 2021-12-20T03:21Z. This was followed by an eruption with dimming, an EUV wave, and post eruptive arcades in SDO AIA 193 and 171 beginning at 2021-12-20T03:15Z. The material is also seen leaving the disk in SDO AIA 304. The source signature is seen as opening field lines in SDO AIA 171.

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 |

This measurement is using SOHO LASCO C2 in SWPC_CAT. The CME is faint in C2 and is not seen in either LASCO C3 or COR2A (Stereo imagery is available). The measurement is based off of the source location of the flare and associated eruption identified in SDO AIA imagery. |
