Note: This CME is visible to the north in GOES CCOR-1 imagery. This event is not seen in SOHO LASCO C2/C3 due to a data gap starting at 2026-02-27T12:12Z related to a SOHO keyhole maneuver. Additionally, this event is not seen in STEREO A COR2 due to a data gap starting at 2026-02-27T15:38Z. The source is likely far-sided, although there is a possibility that a minor eruption centered near N55W05 in SDO AIA 193 imagery starting around 2026-02-27T17:24Z could have been associated with this event. This source is speculative as the time that the CME is observed nearly overlaps with the time the source is observed.
