There was a solar eclipse in the United States today. People where I lived were able to experience 91.32% obstruction of the sun. I love this interactive map of today’s eclipse and past and future ones as well.
Several people have taken and shared marvelous pictures of the eclipse.
Here are a few tweets I saw about eclipses on twitter:
