Note: CME first seen to the NNW in STEREO A COR2 starting at 2026-07-31T03:08Z. While there is not a definite source candidate, this feature could possibly be related to some post eruptive arcades centered around N00W135 seen in STA EUVI 195 and STA EUVI 304 SW of former AR 14493 beginning around 2026-07-31T03:05Z.
