Comet C/2019 U5 (PANSTARRS)

Comet C/2019 U5 (PANSTARRS) was discovered on October 22, 2019, by the Pan-STARRS 1 telescope located in Haleakala, Hawaii. It has a retrograde, hyperbolic-like orbit that is highly tilted (114°) with respect to the orbits of other major solar system objects, suggesting that its origin is most likely from the Oort cloud. On March 30, 2023, it reached its closest approach to the sun, or perihelion, and reached its maximum brightness between January and May 2023. As it continues to move away from the sun, it will gradually become fainter.

Comet C/2019 U5 (PANSTARRS) is currently in the constellation of Sextans.

The current Right Ascension of Comet C/2019 U5 (PANSTARRS) is 10h 29m 36s and the Declination is -04° 34’ 36” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet C/2019 U5 (PANSTARRS) is 13.89 (JPL) while the latest observed magnitude is 12.1 (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/2019 U5 (PANSTARRS) Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet C/2019 U5 (PANSTARRS), 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.
