Note: This CME is visible to the S/SE in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is uncertain, but faint field line movement was visible beyond the SE limb in SDO AIA 171 starting around 2023-04-28T02:00Z. However, there is also a small eruption from AR 3285 (S19W11) starting around 01:30Z which was associated with a C6.7 flare. It was very difficult to measure using far-sided parameters, suggesting this CME may be front-sided. However, if this CME is associated with the eruption from AR 3285 then it would have to be deflected quite significantly from the source.
