When Does Asteroid 1998 OR2 Rise and Set from McMurdo Station, Queen Maud Land?
Asteroid 1998 OR2 is circumpolar and transits at 21:57 UTC (altitude: 31.6°)
The rise and set times are defined as the time at which the upper limb of Asteroid 1998 OR2 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.
