Maximum in Great FallsThis is the moment when the eclipse reaches its greatest magnitude while the entire Moon is above the horizon in Great Falls. The true maximum point of this eclipse cannot be seen in Great Falls because the Moon is below the horizon at that time. Since the Moon is near the horizon at this time, we recommend going to a high point or finding an unobstructed area with free sight to Northeast for the best view of the eclipse.
