Note: [TRUE START TIME 2024-05-04T06:36Z IN LASCO C2 - RETAINING COR2A/T06:53Z START TIME AS NOTIFICATION SENT PRIOR TO UPDATE]. CME to the NE, only seen in STEREO COR2A and later in SOHO LASCO C2/C3 after a delayed backfill. Associated with an M9.1-class flare from AR 3663 (N26W09) which peaked at 2024-05-04T06:19Z, best observed in SDO AIA 131. Also observed as an EUV wave and field line movement deflected to the NE of the region in SDO AIA 171/193/211.

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 |

Measurement of WIDER SHOCK-LIKE FEATURE made with only STEREO COR2A data, as SOHO LASCO C2/C3 data is presently unavailable (further measurements may be made when data available). Source of AR 3663 (N26W09) used as the M9.1 flare is a clear source with some NE deflection observed, and visually fits well in swpc_cat despite the single-coronagraph measurement. |
