Note: This CME is faintly visible to the SW in SOHO LASCO C2, C3, and to the south in STEREO A COR2 imagery. The source appears to be two eruptions in close proximity to each other in the SW quadrant of the Earth-facing disk. A dimming region possibly associated with a faint filament eruption is visible in SDO/AIA 193 starting around 2024-10-04T02:00Z in the SW near ARs 13842, 13839, and 13844 followed by moving/opening field lines visible in SDO/AIA 171 starting around 2024-10-04T03:00Z in the SW below ARs 13844, 13843, and 13836. The moving/opening field lines are largely visible heading to the west while the dimming appears to have some southern directionality. A third separate eruption from AR 13842 (an M4.0 flare) is likely associated with an overlapping CME feature. There is some uncertainty with this analysis due to the multiple eruptions in close proximity and timing to when the CME is first visible in coronagraph imagery. Both SOHO and STEREO A coronagraphs have data gaps during this event.

CME Analysis M2M_CATALOG LE true SWPC_CAT 22.0 -19.0 832.0 C 45.0 2024-10-04T09:16Z Parameters based on best fit of faint leading edge in SOHO LASCO C3 and STEREO A COR2 difference imagery. There is a high level of uncertainty with this analysis due to multiple nearly simultaneous eruptions leading up to the CME in imagery. The width of the CME is very uncertain. 1: Result 1 (2.0 AU)
