When Does Comet 289P/Blanpain Rise and Set? Precise Rise and Set Times
Comet 289P/Blanpain is circumpolar and transits at 23:50 UTC (altitude: 80.4°)
The rise and set times are defined as the time at which the upper limb of Comet 289P/Blanpain 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.
