The Observed Magnitude and Coma Diameter values are derived from the Comet Observers Database by averaging the values reported in recent observations (more recent than 4 days), when available. The Estimated Magnitude comes from the JPL Horizons ephemerides service and might be inaccurate given the highly dynamic and unpredictable behvior of comets. When available please refer to the Observed Magnitude value and consider the Estimated 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.

Distance of Comet 29P/Schwassmann-Wachmann 1 from Earth

The following chart shows the distance of Comet 29P/Schwassmann-Wachmann 1 from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval.

The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 29P/Schwassmann-Wachmann 1 is also available as a real time updated value in the Live Position and Data Tracker.

Light Curve of Comet 29P/Schwassmann-Wachmann 1

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 29P/Schwassmann-Wachmann 1, 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.
