When
Obviously the solar eclipse of August 21, 2017, occurs on August 21, 2017! That's a Monday — in many places, the first day of the new school year.
It takes about 90 minutes for the Moon's dark shadow to cross the country, starting around 10:15 am Pacific time on the West Coast and ending around 2:45 pm Eastern time (11:45 am Pacific time) on the East Coast. When you hear someone say, "the total eclipse lasts 90 minutes," that's what they mean. But that could be misleading: At any given location within the path of the Moon's shadow, the total eclipse lasts at most 2 minutes 40 seconds — don't be late!
The Moon takes its first "bite" out of the Sun, marking the start of the partial eclipse, 1¼ to 1½ hours earlier, around 9:00 am PDT on the West Coast and 1:15 pm EDT on the East Coast. The Moon uncovers the last of the Sun's bright face 2½ to 3 hours after that, around 11:30 am PDT on the West Coast and 4:15 pm EDT on the East Coast. This marks the end of the partial eclipse.

I followed it on TV, internet, and saw the Virginia location version of the partial eclipse. I also followed the progression with my wife, daughter, and the PNF, which made it special. I am happy for all who witnessed the event.
I hope that the scientists who planned years for this event collected the data that they sought. Perhaps it will better enable us to understand the weather on Earth.
