Comet C/2016 R2 (PANSTARRS) is forecast to reach its brightest, at around mag 11.1. It will lie at a distance of 2.79 AU from the Sun, and at a distance of 2.30 AU from the Earth.

From Ashburn (click to change), it will be visible in the evening sky, becoming accessible at around 18:33 (EST) as the dusk sky fades, 71° above your south-eastern horizon. It will then reach its highest point in the sky at 19:16, 74° above your southern horizon. It will continue to be observable until around 00:24, when it sinks to 25° above your western horizon.

For more information about its path across the sky, see In-The-Sky.org's ephemeris page for comet C/2016 R2 (PANSTARRS).

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 Feb 2018).

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.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
