Lunar & Solar Eclipses. The moon's orbit around Earth is slightly tilted with respect to the orbit around the sun. As a result, the moon travels above.

Eclipses. Lunar = Moon. A lunar eclipse is when part or all of the moon is covered by the Earth’s shadow. The moon’s orbit is tipped 5 o relative to.

Solar Eclipse August 21, 2017

Eclipse When one celestial body passes through the shadow of another The umbra is a central cone of darkness which tapers away from the Earth or Moon the penumbra is an outer cone of partial shadow which diverges instead of tapering.

Lunar Eclipse – Earth in the center

Solar Eclipse – Moon in the center An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. Total eclipse of the sun only occurs over a small area Never lasts more than 7 minutes at one location US total eclipse – 2017 One occurs every 18 months

Math is involved!

You MUST wear your solar glasses any time you look toward the sun! DO NOT try to take a picture of the sun – it may damage your phone!!!

Path of total darkness is 70 miles wide. X Path of total darkness is 70 miles wide.

Red is the total eclipse. Watch for the shadow over Fairhope, Alabama.

Next one - 2024 2024 will not be an darker than 2017.

How old will you be in 2052??? TOTAL Solar Eclipse in Fairhope!!!

WEAR THOSE SOLAR GLASSES IF YOU LOOK TOWARD THE SUN!!! Check out the tables of activities, demos and labs. Ice cream and drinks will be sold at the snack bar. Peak darkness will occur at 1:33 pm.
