Comet C/2022 E3 (ZTF) is forecast to reach the brightest point in its 2023 apparition on 1 February. At that time, it will lie at a distance of 1.16 AU from the Sun, and at a distance of 0.28 AU from the Earth.

From Columbus on 1 February it will be visible all night because it is circumpolar. It will be highest in the sky at 22:21, 57° above your northern horizon. At dusk, it will become visible at around 18:56 (EDT), 49° above your northern horizon. It will be lost to dawn twilight at around 06:32, 29° above your northern horizon.

The events that comprise the 2022–2023 apparition of C/2022 E3 (ZTF) are as follows:

Comet brightnesses

Comets are intrinsically highly unpredictable objects, since their brightness depends on the scattering of sunlight from dust particles in the comet's coma and tail. This dust is continually streaming away from the comet's nucleus, and its density at any particular time is governed by the rate of sublimation of the ice in the comet's nucleus, as it is heated by the Sun's rays. It also depends on the amount of dust that is mixed in with that ice. This is very difficult to predict in advance, and can be highly variable even between successive apparitions of the same comet.

In consequence, while the future positions of comets are usually known with a high degree of confidence, their future brightnesses are not. For most comets, we do not publish any magnitude estimates at all. For the few comets where we do make estimates, we generally prefer the BAA's magnitude parameters to those published by the Minor Planet Center, since they are typically updated more often.

No estimate for the brightness of comet C/2022 E3 (ZTF) is currently available.
