This image shows six days of apparent change in Comet 2022 E3 ZTF (Jan 24-29), The comet displayed a much more prominent ion tail and anti-tail (first image left on Jan 24, 2023) and as the comet presented a different perspective as it moved from the plane of the Earth's orbit the observed structure of the coma and tails change. The observed ion tail is rotating clockwise as the comet moves in the sky and from the perspective of observers on Earth. Both the comet and Earth move quickly in their orbits resulting in observable changes within a day's time.
