When Does Comet 22P/Kopff Rise and Set from Uummannaq, Greenland?
Comet 22P/Kopff is circumpolar and transits at 17:41 UTC (altitude: 39.4°)
The rise and set times are defined as the time at which the upper limb of Comet 22P/Kopff 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.
