Comet 154P/Brewington will make its closest approach to the Sun, at a distance of 1.56 AU.

From Fairfield the 2024 apparition of 154P/Brewington will progress as follows:

A more detailed table of 154P/Brewington's position on each night is available here. A diagram of the orbit of 154P/Brewington is available here.

At the moment of perihelion it will not be observable – it will reach its highest point in the sky during daytime and will be no higher than 11° above the horizon at dawn.

Finder chart

The chart below shows the path of 154P/Brewington over the course of its apparition, as calculated from the orbital elements published by the Minor Planet Center (MPC). It is available for download, either on dark background, in PNG, PDF or SVG formats, or on a light background, in PNG, PDF or SVG formats. It was produced using StarCharter.

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 For most comets, we do not publish any magnitude estimates at all.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 154P/Brewington is currently available.

The comet's position at perihelion will be:

Object Right Ascension Declination Constellation Magnitude
Comet 154P/Brewington 03h04m40s 26°28'N Aries 11.4

The coordinates are given in J2000.0.
