Comet 62P/Tsuchinshan will make its closest approach to the Sun on 17 January, at a distance of 1.27 AU.

From Fairfield on the day of perihelion it will be visible in the evening sky, becoming accessible around 18:02 (EST), 25° above your north-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 23:50, 85° above your southern horizon. It will continue to be observable until around 05:58, when it sinks below 21° above your north-western horizon.

The events that comprise the 1992–1993 apparition of 62P/Tsuchinshan 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 For most comets, we do not publish any magnitude estimates at all.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 62P/Tsuchinshan is currently available.

The comet's position at perihelion will be:
