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.
