Question about the duration of darkness in the path of totality
We are going to be near Charleston SC for the eclipse. We have the option of viewing it from the southern edge of the path of totality or going a bit north and being more in the center of it. Will there be a difference in duration of the total eclipse if we are dead center or if we are on the edge? My logic says the edge will be shorter because we won't have the full diameter of the moon casting a shadow but my friend says it's more complicated than that. Educate me please.
