You made me look. Above is a map of Africa showing the path of the eclipse. It appears that that dark blob on the original video is the 90% path. Yeah - I have no idea what the shadow would look like from space. (Hmm - wouldn’t the space station have images of it?)
The diameter of the moon’s shadow on the earth averages about 100 miles.
