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.
