45P/Honda-Mrkos-Pajdusakova reaches its brightest

Comet 45P/Honda-Mrkos-Pajdusakova is forecast to reach its brightest, at around mag 6.5. It will lie at a distance of 0.95 AU from the Sun, and at a distance of 0.09 AU from the Earth.

From Ashburn, it will be visible in the dawn sky, rising at 01:47 (EST) – 5 hours and 19 minutes before the Sun – and reach an altitude of 46° above the eastern horizon before fading from view as dawn breaks at around 06:01.

This event was automatically generated on the basis of orbital elements published by the Minor Planet Center (MPC), and is updated daily (last update, 15 Jan 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.

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.
