Comet C/2022 U1 (Leonard)

Comet C/2022 U1 (Leonard) is currently in the constellation of Cassiopeia. The current Right Ascension of Comet C/2022 U1 (Leonard) is 01h 06m 08s and the Declination is +58° 29’ 03” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet C/2022 U1 (Leonard) is 18.07 (JPL) while the latest observed magnitude is 19.1 (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.

Comet C/2022 U1 (Leonard) Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet C/2022 U1 (Leonard), 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.
