C/2015 F5 (SWAN-Xingming) reaches its brightest

Comet C/2015 F5 (SWAN-Xingming) is forecast to reach its brightest, at around mag 6.1. It will lie at a distance of 0.36 AU from the Sun, and at a distance of 0.67 AU from the Earth.

From Fairfield however, it will not be readily observable since it will be very close to the Sun, at a separation of only 7° from it.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

For more information about its path across the sky, see In-The-Sky.org's ephemeris page for comet C/2015 F5 (SWAN-Xingming).

This event was automatically generated on the basis of orbital elements published by the Minor Planet Center (MPC), and is updated daily (last update, 20 Mar 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.

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.


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.
