An annular eclipse of the sun took place on May 21, 2012, and its shadow was visible from satellite imagery (A previous example from this blog is here). The loop above shows MTSAT imagery; the shadow of the eclipse emerges shortly after sunrise and tracks northeastward into the Pacific Ocean. The loop below shows GOES-West imagery, tracking the shadow from the north Pacific Ocean to the coast of North America around sunset.

A portion of the eclipse shadow could also be seen on an AWIPS image of POES AVHRR 0.86 µm visible channel data (below), extending from the far northern Pacific Ocean across the Aleutian Islands and into the southern Bering Sea.
