论文摘要
覆盖背景另一个的天体的晦涩被称为``等级日食''。最明显的情况是，月食期间，恒星或行星将被月球隐藏起来。太阳系的四个对象将排队。我们研究了有关可见性和周期性区域的这种现象。存在一个视差场，以限制观察的机会。从不同的观看角度进行分析，保留了中世纪的历史记录。此外，我们提供了从0到4000 AD的活动列表。由此，很明显，木星最常参与此类眼镜，因为它的轨道倾斜度很小。高包装轨道降低了该物体与月食的粘合物的巧合的可能性。
The obscuration of a celestial body that covers another one in the background will be called a ``hierarchical eclipse''. The most obvious case is that a star or a planet will be hidden from sight by the moon during a lunar eclipse. Four objects of the solar system will line up then. We investigate this phenomenon with respect to the region of visibility and periodicity. There exists a parallax field constraining the chances for observation. A historic account from the Middle Ages is preserved that we analyse from different viewing angles. Furthermore, we provide a list of events from 0 to 4000 AD. From this, it is apparent that Jupiter is most often involved in such spectacles because its orbit inclination is small. High-inclination orbits reduce the probability to have a coincidence of an occultation of that object with a lunar eclipse.
