Comet 144P/Kushida is forecast to reach the brightest point in its 2024 apparition on 8 January. At that time, it will lie at a distance of 1.41 AU from the Sun, and at a distance of 0.61 AU from the Earth.

From San Diego on 8 January it will be visible in the evening sky, becoming accessible around 18:00 (PDT), 58° above your south-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 19:52, 71° above your southern horizon. It will continue to be observable until around 00:44, when it sinks below 21° above your western horizon.

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 For most comets, we do not publish any magnitude estimates at all.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.

Based on the magnitude parameters published for this comet by the BAA Comet Section, we estimate that it may be around mag 7 on 8 January 2024. This estimate is based on observations that the BAA has received from amateur astronomers, assuming that its current level of activity will remain constant.

This comet is not expected to be visible to the naked eye, but might be visible through bird-watching binoculars.

The comet's position on 8 January 2024 will be:

Object Right Ascension Declination Constellation Magnitude
Comet 144P/Kushida 03h16m40s 14°25'N Aries 7.2

The coordinates are given in J2000.0.
