Year 2015 Earth Day Earthshine

On Earth Day eve, 2015-04-21, three days past the new moon of 4/18, here is a picture of doubly reflected sunlight. The sun has set, that is we can't see it because earth has turned. But we can see sunlight reflected from the moon and also reflected from earth that reflects it to the moon. The dark part of the moon is faintly illuminated by sunlight reflected from earth shortly after sunset. 40 minutes later, in this case.
