As the eclipse progresses it passes over the date line headed eastward. This annular eclipse will be visible in the late afternoon in the USA on the 20th (local date/time). As the eclipse path meets the coast the sun will only be about 20-30 degrees above the horizon (30 degrees at the start of the partial phase, just over 20 during the annular phase).
Should be visible in New Mexico.
