Note: [TRUE START TIME 2024-05-04T00:00Z IN LASCO C2 - RETAINING COR2A/T01:53Z START TIME DUE TO DELAY]. CME seen to the NE in STEREO COR2A and later in SOHO LASCO C2/C3 after a delayed backfill. STEREO had also just left a data gap, spanning 2024-05-03T11:23Z to 2024-05-04T01:53Z, which is marked as the first visible frame for this CME. The source is not clear in EUV imagery outside of SDO AIA 131 (detailed below). The best sources for this are two of three flares from AR 3663 (around ~N26W03 at this time). These flares, best observed in SDO AIA 131, are an M1.0 and M2.4 peaking at 2024-05-03T23:16Z and 2024-05-03T23:30Z respectively. Additionally, a third flare from AR 3663 occurring just after the CME is visible in SOHO, an M1.6 peaking at 2024-05-04T00:36Z, launched a small front visible ~2024-05-04T02:12Z in SOHO LASCO C2 for 3-4 frames before likely colliding into this CME--so all three of these flares were measured as one.

CME Analysis M2M_CATALOG LE true SWPC_CAT -12.0 47.0 446.0 S 17.0 2024-05-04T07:34Z Updated BULK measurement using now available SOHO LASCO C2/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, but this was the only way triangulation between the coronagraphs would fit. Not modeled Tony Iampietro on 2024-05-07T18:56Z
CME Analysis M2M_CATALOG LE false SWPC_CAT -1.0 29.0 648.0 C 13.0 2024-05-04T04:52Z Measurement 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 used as an initial fit given the region's history of flaring activity and eruptions, alongside evidence from CME 2024-05-04T06:53Z looking visually similar, to pinpoint this source lat/lon despite the one coronagraph measurement. Medium confidence in this measurement. 1: Result 1 (2.0 AU)
