Napa is a long way from the Maumee River, but I happened to be there during the recent partial solar eclipse.
Above is an image of the moon passing across the sun as seen through a pinhole projected onto a wall. Below you can see the same pinhole effect produced by the intersections of tree leaves, casting multiple shadows onto the sidewalk.
Another interesting celestial event occurs June 5 when Venus crosses the sun. This can be seen in the afternoon if you live in the Americas. For more information about safely viewing this event, go to Astro Bob.
