NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 1I/2017 U1 (Oumuamua) brightness
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 1I/2017 U1 (Oumuamua), 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.
Asteroid 1I/2017 U1 (Oumuamua) rise and set times
The rise and set times are defined as the time at which the upper limb of Asteroid 1I/2017 U1 (Oumuamua) touches the horizon, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
