Note: This CME is visible to the SW in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely far-sided as there are no clear source signatures on the Earth-facing disk. Additionally, faint eruption material can be seen from beyond the SW limb in SDO AIA 171 starting around 2023-05-17T07:45Z, confirming that this is most likely a far-sided event.
