Comet A/2019 U6 is forecast to reach its brightest. It will lie at a distance of 0.92 AU from the Sun, and at a distance of 0.83 AU from the Earth.

From Fairfield however, it will not be observable – it will reach its highest point in the sky during daytime and will be 3° below the horizon at dusk.

The chart below shows the path of A/2019 U6 over the course of its apparition, as calculated from the orbital elements published by the Minor Planet Center (MPC).

The chart 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.

Alternatively, you can create a textual listing of the comet's position using In-The-Sky.org's ephemeris generator.

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 For most comets, we do not publish any magnitude estimates at all.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 5 on 22 June 2020. This estimate is based on observations that the BAA has received from amateur astronomers, assuming that its current level of activity will remain constant.

The comet's position on 22 June 2020 will be:

Object Right Ascension Declination Constellation Magnitude
Comet A/2019 U6 09h23m10s -09°31' Hydra 4.9

The coordinates are given in J2000.0.
