Note: [TRUE START TIME 2024-05-05T01:12Z IN LASCO C2 - RETAINING COR2A/T02:09Z START TIME AS NOTIFICATION SENT PRIOR TO UPDATE]. Narrow northern CME with filamentary structures which is similar to some previous CMEs from AR 3663. This CME is very likely associated with the M9.0 and M8.4 flares from AR 3663, peaking at 2024-05-04T23:48Z and 2024-05-05T01:27Z respectively, however no clear additional lower coronal signatures have been found in EUV imagery. This CME appears as two separately emerging fronts (T01:12Z and T02:12Z) which combine early in SOHO LASCO C2 imagery--which has now backfilled as of 2024-05-07 that prevented full real-time analysis for flare association.

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 |

Updated BULK measurement using now available SOHO LASCO C3 imagery in addition to STEREO COR2A, to include more imagery and better triangulate the lat/lon. Noting some heavy deflection away from the source (potentially evident in SDO imagery with some field line movement to the NE of the eruption), but this was the only way triangulation between the coronagraphs would fit. |
