Please enjoy eclipses safely! Do not use your regular sunglasses. Do not try to look through a plastic water bottle or tinted window. Do not use anything other than the proper solar viewing glasses that meet the required safety standards. Be safe and get your own eclipse glasses, safe for the direct observation of the Sun!

If you are within the path of totality, there are a few minutes where you can safely remove your solar viewing glasses and enjoy the brilliance of the eclipse with your own eyes, but only during that moment of complete totality.

"A solar eclipse is the alignment of the Sun, Moon, and you." -Tyler Nordgren

Most importantly, get outside and experience the wonder of your place in space.
