Note: Approximate analysis of the second front of this halo CME (possibly its bulk), based on a fit with two coronagraphs. For STEREO A COR2 imagery only one timestamp is available (bc of a large data gap), adding to the uncertainty of analysis. Analysis is supported by the location of a large backsided active region in helioseismology imagery from GONG - likely the former AR 13679 that was around lat/lon -8/-170 at the time of this event. In addition, STIX instrument on Solar Orbiter detected a significant flare at 2024-06-01T18:45Z.
