Comet C/2018 Y1 (Iwamoto) is forecast to reach its brightest, at around mag 6.4. It will lie at a distance of 1.28 AU from the Sun, and at a distance of 0.30 AU from the Earth.

From Fairfield, it will be visible between 19:28 and 05:33. It will become accessible at around 19:28, when it rises 21° above your eastern horizon, and then reach its highest point in the sky at 00:32, 65° above your southern horizon. It will become inaccessible at around 05:33 when it sinks to 22° above your western horizon.

For more information about its path across the sky, see In-The-Sky.org's ephemeris page for comet C/2018 Y1 (Iwamoto).

This event was automatically generated on the basis of orbital elements published by the Minor Planet Center (MPC), and is updated daily (last update, 18 Apr 2019).

Note that the future positions of comets are typically known with a high degree of confidence, but their brightnesses are often much more unpredictable, since it is impossible to predict with certainty how they will respond as they move closer to the Sun. Magnitude estimates should be assumed to be highly provisional more than a few weeks in advance.
