On August 21, 2017, millions of people across the United States had the opportunity to witness the unique and unforgettable moment when the Moon itself completely blocks the sun´s disc. The poster above is a composite result of a series of shots taken in sequence from Stanley Lake, Idaho, from the beginning of partial phase (right opaque listed disc) up to the totality (in the center) and the final stage of partiality (opaque listed disc at left). During totality, the moon´s dark disc completely covers the entire disc of the sun, what give us the unique opportunity to watch the Solar Corona (the most outer atmosphere of the sun), visible in the image above as the background faint white light, although, due to the tremendous variance of brightness in the dynamic range between the surface of the sun and Corona, is not possible to see both of them at the same time. In this this final composite poster of the entire sequence, we are able to safely appreciate the sun´s surface with two group of Sunspots – known as Active Regions (AR) AR2672 and AR2671 mixed with the inner and most outer Solar Corona only visible during totality event.
