Closest approach of Comet C/2015 ER61 (PANSTARRS) to Earth

Between January 2013 and December 2100 the closest approach of Comet C/2015 ER61 (PANSTARRS) to Earth happens on Wed Apr 19 2017 at a distance of 1.17846421 Astronomical Units, or 176,295,737 kilometers:

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

Comet C/2015 ER61 (PANSTARRS) brightness

The current visual magnitude of Comet C/2015 ER61 (PANSTARRS) is 22.17.

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 C/2015 ER61 (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.

Comet C/2015 ER61 (PANSTARRS) rise and set times

Today's Comet C/2015 ER61 (PANSTARRS) rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

The rise and set times are defined as the time at which the upper limb of Comet C/2015 ER61 (PANSTARRS) 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.
