Well in my experience with Solar Eclipses is that before it starts or before it is covering the moon is covering the sun there is like a shadow on one side of the sun and after the hours or minutes go by all around you everything is getting darker and a little colder than it was a few moments ago so what it would look like is something is in front of the sun or its like the moon got so close to the sun that it just blocked it and also some of the sun's rays surround the moon.
