Quick Facts:

·       In Zip code 75214, we will see a partial eclipse.

·       The moon will begin to “cover the sun” at 11:40 AM CDT. Our Earth rotates into the Moon’s shadow. This blocks some of the sun from our view. The coverage will continue to increase until it reaches its maximum coverage at 1:10 PM CDT, at which point the moon will be covering 75% of the sun. We will begin to rotate out of the moon’s shadow- and more of the sun will become visible- until 2:39 PM CDT, at which point the sun will be completely visible again.

·       Safety: You must use special glasses or lenses when looking directly at the sun during a partial eclipse. It is safe to look at a total eclipse only during totality. Sunglasses do not protect your eyes.
