NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Comet 29P/Schwassmann-Wachmann 1 brightness

The current visual magnitude of Comet 29P/Schwassmann-Wachmann 1 is 15.16.


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.

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.

Comet 29P/Schwassmann-Wachmann 1 rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's Comet 29P/Schwassmann-Wachmann 1 rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 76.5°
Max altitude: 52.0°
Azimuth: 283.5°
Comet 29P/Schwassmann-Wachmann 1 is above the horizon from Greenwich, United Kingdom

The rise and set times are defined as the time at which the upper limb of Comet 29P/Schwassmann-Wachmann 1 touches the horizon, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
