Comet C/2023 P1 (Nishimura) has been discovered on August 11, 2023 by amateur astronomer Hideo Nishimura. The comet will pass its perihelion on September 18, 2023, at a distance of 34 million kilometers from the Sun (or 0.23 Astronomical Units). During its journey, it will reach the closest approach to Earth on September 13, 2023 at a distance of 128 million kilometers (or 0.85 Astronomical Units). The maximum brightness will happen on September 17, when the comet is predicted to reach magnitude 5, which could make it potentially visible to the naked eye. On that day, from the Northern Hemisphere, attempts to locate comet C/2023 P1 (Nishimura) in the sky - which will be in the constellation of Virgo - should be made soon after sunset, as it will set about one hour after the Sun. Useful maps to locate the comet from your location can be obtained using TheSkyLive Planetarium.

The observed values of Magnitude,Coma Diameter and Tail Length are derived from the most recent observation recorded at the Comet Observers Database. The value of Predicted Magnitudecomes from the JPL Horizons ephemerides service and, in the case of comets, might beinaccurate given the highly dynamic and unpredictablebehavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted Magnitude as adirectional indication. We acknowledge with thanks the comet observations from the COBS Comet ObservationDatabase contributed by observers worldwide and used in this table toreport recent comet observations.

The following chart is the predicted light curve(visual magnitude as a function of time) of Comet C/2023 P1 (Nishimura),according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuraciesfor objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepanciesbetween the observed and predicted brightness because of their highly dynamic behaviour.
