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 Magnitudecomes from the JPL Horizons ephemerides service and, in the case of comets, might beinaccurate given the highly dynamic and unpredictablebehavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted Magnitude as adirectional indication. We acknowledge with thanks the comet observations from the COBS Comet ObservationDatabase contributed by observers worldwide and used in this table toreport recent comet observations.

The distance of Comet C/2023 A1 (Leonard) from Earth is currently
The following chart shows the distance of Comet C/2023 A1 (Leonard) from Earth as a function of time.In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.

The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth.The value of the distance of C/2023 A1 (Leonard) from Earth is also available as a real time updated value in theLive Position and Data Tracker.
Between 1 January 2014 and 31 December 2099,the closest approach ofComet C/2023 A1 (Leonard) to Earth happens on Thu Mar 2 2023 at a distance of 1.186987 Astronomical Units, or177,570,761 kilometers:
NOTE: values for the closest approach are computedwith a sampling interval of 1 day.
The following chart is the predicted light curve(visual magnitude as a function of time) of Comet C/2023 A1 (Leonard),according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuraciesfor objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepanciesbetween the observed and predicted brightness because of their highly dynamic behaviour.
