NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 1999 KW4 Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 1999 KW4, 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.
