There was an annual solar eclipse that was visible near me on a lovely morning of October 14th (when the clouds parted enough). Some people celebrated an occasion with a family outing and were well-equipped, some did not even notice. Looking at the sun (even when it is covered by the moon) is bad for your eyes! There is an endless number of ways to make shadows which all turn into crescents one way and then another. I am so glad it was Saturday!
