The rise and set times are defined as the time at which the upper limb of Comet 20D/Westphal 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.
