Here's something to look out for during the eclipse.
The eclipsed Moon is illuminated by reddish light. This is light that has come the long way round from the Sun through the upper atmosphere. As the light travels, the other colors are scattered, leaving the red. But some of the light also passes through the ozone layer. This light looks more turquoise, because the ozone absorbs the red light.
The best way to look for the turquoise is to use binoculars either towards the beginning or end of totality. Here is an
