Comet C/2015 V2 (Johnson) will make its closest approach to the Sun, at a distance of 1.65 AU.

From Seattle, it will become visible around 22:53 (PST) as the dusk sky fades, 50° above your southern horizon. It will then sink towards the horizon, setting at 05:02.

Based on the absolute magnitude published for this comet by the British Astronomical Association's Comet Section, we estimate that it may be around mag 8 at perihelion.

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/2015 V2 (Johnson) 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.

Alternatively, you can create a textual listing of the comet's position using's ephemeris generator.
