Comet 287P/Christensen

Altitude: -46.1°   Azimuth: 304.3°   Direction: North-West

Comet 287P/Christensen is currently in the constellation of Aquarius. The current Right Ascension of Comet 287P/Christensen is 22h 47m 21s and the Declination is -18° 40’ 43” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet 287P/Christensen is 18.17 (JPL).

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 Magnitude comes from the JPL Horizons ephemerides service and, in the case of comets, might be inaccurate given the highly dynamic and unpredictable behavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted Magnitude as a directional indication. We acknowledge with thanks the comet observations from the COBS Comet Observation Database contributed by observers worldwide and used in this table to report recent comet observations.

Comet 287P/Christensen Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 287P/Christensen, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
