When Does Comet 80P/Peters-Hartley Rise and Set?
Comet 80P/Peters-Hartley is circumpolar and transits at 23:49 UTC (altitude: 78.1°)
The rise and set times are defined as the time at which the upper limb of Comet 80P/Peters-Hartley touches the horizon, taking into account the effect of the atmospheric refraction. Since the atmosphere conditions cannot be modeled precisely, the times reported here should be considered correct with an approximation of a few minutes.
