Distance of Comet C/2014 A4 (SONEAR) from Earth

The following chart shows the distance of Comet C/2014 A4 (SONEAR) from Earth as a function of time. Distance data is sampled with a 2 days interval, so please keep in mind that there might be inaccuracies around the time of closest approach for objects passing extremely close to Earth. Real time current distance of Comet C/2014 A4 (SONEAR) from Earth is also available.

Light Curve of Comet C/2014 A4 (SONEAR)

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet C/2014 A4 (SONEAR), according to the most recent ephemerides data.

The magnitude data is sampled with a 2 days interval, so there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. Also, for comets there could be large discrepancies between the observed and predicted brightness because of the their highly dynamic and unpredictable behaviour. To get precise information about the current magnitude of Comet C/2014 A4 (SONEAR), updated in real time, please go to the Comet C/2014 A4 (SONEAR) live tracker page.
