Temporal shape evolution of the blending lines in the area surrounding the 4341 Å and 4650 Å V2 and V1 oxygen multiplets. Days since detection are marked in the top-right-corner of each subplot in the V1 column. The most pronounced flaring episodes are between days 140–150 post-discovery. Note in the V1 multiplet column plot (right hand side) a saddle-shaped He II line at 4686 Å fits the 4676 and 4696 Å lines if they are the red and blue wings of the He II line.
