Comet C/2014 A4 (SONEAR) Light Curve

The following chart is the predicted light curve according to the most recent C/2014 A4 (SONEAR) ephemerides data.

Data is sampled with a 2 days interval, so there might be inaccuracies for objects changing brightness very rapidly. Also, for comets there might be in general large discrepancies between the observed and predicted brightness because of the their highly unpredictable behaviour.

Comet C/2014 A4 (SONEAR) Distance from Earth

The following chart shows the distance of Comet C/2014 A4 (SONEAR) from Earth as a function of time.

Data is sampled with a 2 days interval, there might be inaccuracies for objects passing very close to Earth, at the time of their closest distance to the earth.
