Caption: Figure 7.
Same as Figure 6, but comparing the quiescent comet to the July 18 outburst (image taken on 2021 July 19 09:53:16 UTC, 13 hr after the comet was seen outbursting on July 18 (2021 July 18 22:17:16 UTC), where the comet’s outbursting activity is more visible). Light-blue arrows point at the two sides of an asymmetric cone of ejecta material with a broad opening angle of ∼130∘ pointing in the antisunward direction.
