As a partial solar eclipse, it was visible on land from Nunavut in northern Canada to as far south as northern South America. In northwestern Europe and Africa, it was partially visible in the late evening. In Asia it was visible only at the eastern extremity, the Chukchi Peninsula.

Question: when is the full eclipse supposed to happen?
Step-by-step reasoning process: The relevant sentence in the passage is: The solar eclipse of August 21, 2017 was a total eclipse visible within a band across the entire contiguous United States, passing from the Pacific to the Atlantic coasts.
