Comet C/2022 A2 (PANSTARRS) is a comet discovered by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) on January 10, 2022. The comet has a parabolic-like and retrograde orbit with a perihelion distance of 1.73 astronomical units (AU). It has reached its maximum brightness in January 2023, during its perihelion passage, and now it is becoming fainter as it is moving away from the sun.

Tail Length (COBS) n/a

Observation Date (COBS) n/a

Predicted Magnitude (JPL) 23.40

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.

Light Curve

The following chart shows the light curve of comet C/2022 A2 (PANSTARRS), i.e., its apparent magnitude as a function of time. The curve is calculated using the latest ephemerides provided by JPL Horizons. The magnitude data is sampled with the interval of 2 days. Because of this sampling, inaccuracies may occur for objects that have large variations of brightness over a few days. For comets, large discrepancies can arise between the calculated brightness and the observations due to their highly dynamic, and not always precisely predictable, behavior.
