Comet C/2007 N3 (Lulin) will make its closest approach to the Earth on 25 February, at a distance of of 0.39 AU.

From Fairfield on the day of perigee it will be visible between 20:19 and 05:20. It will become accessible at around 20:19, when it rises to an altitude of 19° above your eastern horizon. It will reach its highest point in the sky at 00:50, 53° above your southern horizon. It will become inaccessible at around 05:20 when it sinks below 19° above your western horizon.

The events that comprise the 2008–2009 apparition of C/2007 N3 (Lulin) 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 For most comets, we do not publish any magnitude estimates at all.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 C/2007 N3 (Lulin) is currently available.
