Objects: 88P/Howell

Comet 88P/Howell will make its closest approach to the Sun on 20 May, at a distance of 1.36 AU.

From Fairfield on the day of perihelion it will not be observable – it will reach its highest point in the sky during daytime and will be no higher than 16° above the horizon at dawn.

The events that comprise the 1982 apparition of 88P/Howell 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 For most comets, we do not publish any magnitude estimates at all.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 88P/Howell is currently available.

The comet's position at perihelion will be:
