Not in the total path but 80%. Will see if my welding helmet has a dark enough lens. When i was a kid i seen one, Wild to see it go dark in the middle of the day!
I watched it through my welding helmet. Probably better then watching it through cheap sunglasses. If your helmet is an auto darkening one, you might want to be sure its darkened before looking at the sun. I watched through my old school fixed lens helmet with a 12 or 13 tint (I think). Just after the start and just before the end have the most intense brightness, when the sun is almost covered the remaining light seems to be more focused.
