Note: The CME front is lopsided due to the eruption deflection and partial overlap with CME 2025-11-29T16:00Z. Best attempt at triangulating and following the leading edge direction is taken between GOES CCOR-1 and STEREO A COR2, which does miss some material on the northern edge that cannot fit in the swpc_cat tool's width due to the elongated CME shape, as such the half-width may be wider than 27 degrees.
