Comet C/2014 UN271 (Bernardinelli-Bernstein)
Comet C/2014 UN271 (Bernardinelli-Bernstein) is currently in the constellation of Horologium. The current Right Ascension of Comet C/2014 UN271 (Bernardinelli-Bernstein) is 03h 12m 35s and the Declination is -57° 54’ 29” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current estimated magnitude of Comet C/2014 UN271 (Bernardinelli-Bernstein) is 18.35 (JPL) while the latest observed magnitude is 16.1 (COBS).
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.
