Overview
The 2027 lunar shadow first embraces the Earth over the sub-tropical mid Atlantic in a region of moderately cloudy skies well to the north of the hurricane-breeding zone off western Africa. The umbral path misses the islands of Porto Santo and Madeira by a meagre 70 km on its eastward trek, choosing instead to make landfall in Spain and Morocco six minutes later. For the next 4,000 km, it first skips along the Mediterranean shore before gradually turning to a southeast heading. The turn to more southerly latitudes comes with increasing amounts of cloud, but, except in the mountains of Arabia, most of that intrudes after the path heads out across the Indian Ocean, toward its ending near the remote atoll of Diego Garcia.

The Astronomical League provides many different Observing Programs. These Observing Programs are designed to provide a direction for your observations and to provide a goal. The Observing Programs have certificates and pins to recognize the observers’ accomplishments and for demonstrating their observing skills with a variety of instruments and objects.
The Association of Lunar and Planetary Observers was founded in 1947 and promotes observing of the solar system. Both amateur and professional astronomers work together to further our understanding of the universe.
