When Does Pioneer 10 Rise and Set from Gällivare, Sweden?
Pioneer 10 is circumpolar and transits at 13:04 UTC (altitude: 48.9°)
The rise and set times are defined as the time at which the upper limb of Pioneer 10 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.
