Fort McMurray · next 30 nights. Times when the planet is at least 20° above the horizon during astronomical darkness.
These are position calculations, not visibility guarantees. Planets can also be observed in twilight; this planner deliberately selects darker windows. Clouds, haze, steady air and local obstructions still matter. A telescope is needed for planetary detail.
