Comet C/2015 O1 (PANSTARRS) will make its closest approach to the Sun, at a distance of 3.73 AU.
From Ashburn (click to change), it will be visible in the dawn sky, rising at 22:11 (EDT) – 8 hours and 46 minutes before the Sun – and reach an altitude of 78° above the eastern horizon before fading from view as dawn breaks at around 05:52.
For more information about its path across the sky, see In-The-Sky.org's ephemeris page for comet C/2015 O1 (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, 20 May 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.
