Comet C/2018 W2 (Africano) is forecast to reach its brightest. It will lie at a distance of 1.49 AU from the Sun, and at a distance of 0.50 AU from the Earth.

From Cambridge, it will be visible all night. It will become visible around 19:41 (EST) as the dusk sky fades, 24° above your eastern horizon. It will then reach its highest point in the sky at 00:29, 64° above your southern horizon. It will be lost to dawn twilight around 05:28, 22° above your western horizon.

Based on the absolute magnitude published for this comet by the British Astronomical Association's Comet Section, we estimate that it may reach a peak brightness of around mag 9.

This comet is not expected to be visible to the naked eye, but might be visible through bird-watching binoculars. The brightnesses of comets are often highly unpredictable, since it is impossible to predict with certainty how they will respond as they are heated by the Sun as they move into the inner solar system. Magnitude estimates should be assumed to be highly provisional more than a few weeks in advance.

The path of the comet, on the other hand, can reliably be predicted. The chart below shows the path of C/2018 W2 (Africano) over the course of its apparition. It was produced using StarCharter and 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.
