Comet 71P/Clark is forecast to reach its brightest, at around mag 11.1. It will lie at a distance of 1.60 AU from the Sun, and at a distance of 0.60 AU from the Earth.

From Ashburn (click to change) however, it will not be readily observable since it will lie so far south that it will never rise more than 20° above the horizon.

For more information about its path across the sky, see In-The-Sky.org's ephemeris page for comet 71P/Clark.

This event was automatically generated on the basis of orbital elements published by the Minor Planet Center (MPC), and is updated daily (last update, 28 Jun 2017).

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 exact position of comet 71P/Clark will be:

Object Right Ascension Declination Constellation Magnitude
Comet 71P/Clark 16h29m00s -30°38' Scorpius 11.1

The coordinates are given in J2000.0.

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.
