Note: BULK measurement using both coronagraphs to triangulate the same features, using AR 3664 as the source. This CME front is notably asymmetric in all imagery, but there is high confidence in all three "nodes" in different directions pertaining to the same CME front directed towards Earth from this same eruption. The right hand boundary was mainly used, matching the half-width to the peaks of each node of the asymmetric front, which tracked surprisingly well once aligned.
